» The Jury is made up of a panel of art experts and enthusiasts who judged a varied selection of works. Most pieces have been specially created for the » Amsterdam Light Festival and have never previously been exhibited. The city will be awash with light sculptures, projections and installations by contemporary local and international artists. The boat route, “Water Colors”, will take visitors past artworks along the Amstel and the city’s famous network of canals. The walking route, “Illuminade”, winds through the city center. Light will play a central role throughoutthe city during the festival, as museums and institutions organize light-related activities and treat visitors to some of the latest innovations in the world of light art.

The theme for the festival, ‘A Bright City’, challenges artists to create a tribute to modern Amsterdam. The resulting artworks will present a unique take on contemporary urban life in the Dutch capital. The Austrian lighting solutions partner Zumtobel is acting as a key partner for the realization of central artworks at the Amsterdam Light Festival by providing advice and lighting solutions developed specifically for the event. As well as sponsoring the whole festival, Zumtobel is also helping to realize two major installations: INTREPID, The Paper Boat by Katja Galyuk/City+Light and Re(bi)cycle Dome by Vasili Popov.

“By partnering with the Amsterdam Light Festival, we are fostering our strong engagement with light and art,” says Stefan von Terzi, Marketing Director at Zumtobel. “We are looking forward to taking part in one of the largest light festivals in Europe, supporting artists and designers both with our lighting solutions and our experience.”

Zumtobel to open LightLab in Amsterdam
On 16. January 2015, Zumtobel will officially open a brand new creative design center in the city of Amsterdam. The opening will be accompanied by the first ever exhibition of their renowned Masterpieces Collection, containing unique light sculptures by Zahad Hadid, Olafur Eliasson and Daniel Libeskind. The Masterpieces Collection will be then on show to the public at the well-known Amsterdam Center for Architecture (ARCAM) until the middle of March 2015.

Zumtobel. The Light.

The » global user study on lighting quality perceived in offices conducted by Zumtobel and » Fraunhofer IAO has shown that office users' preferences with regard to colour temperature differ very much. The range of colour temperatures perceived as ideal is usually between 3000 K and 6000 K, with a clearly marked majority preference for 4000 K and 5000 K scenarios. The study also shows that office users rate their situation at work significantly higher where it is possible for them to adjust the lighting to their needs. However, 57.4 per cent of those surveyed, i.e. more than half of them, have no influence – or only to a limited extent – on lighting control and therefore cannot optimise the lighting situation accordingly. A factor that has a major impact on people's sense of well-being and consequently their satisfaction at the workplace. As continuously colour temperature-adjustable LED luminaires cater for these individual user needs the most effectively, Zumtobel has added tunableWhite technology to its range of luminaires.

LIGHT FIELD evolution tunableWhite
Zumtobel meets users' various requirements by providing a lighting solution that combines innovative LED technology with sophisticated design quality. Thanks to tunableWhite technology, users can adjust the colour temperature of the » LIGHT FIELDS evolution LED luminaire range continuously between 3000 K and 6000 K. The LED luminaire range uses a consistent design language. From recessed and surface-mounted through to free-standing or pendant luminaires: each luminaire incorporates a specifically developed brilliant optic. For the user this means that LIGHT FIELDS evolution featuring tunableWhite technology not only adjusts colour temperature to meet individual requirements but also provides perfect lighting quality at the workstation.

MILDES LICHT V tunableWhite
The » MILDES LICHT V recessed luminaire provides offices with light that is similar to daylight. The versatile recessed LED luminaire ensures gentle, glare-free light distribution without any distracting hard shadows, allowing for balanced illumination of task areas, walls and the ceiling. This creates an open, bright room atmosphere. MELLOW LIGHT V tunableWhite provides additional flexibility and customisation: the luminaire can be integrated into a lighting management system such as LITECOM in next to no time, and can be continuously adjusted in the range between 3000 K and 6000 K.

ONDARIA tunableWhite
With its opal, uniform luminous panel and circular design, » ONDARIA creates a pleasant atmosphere and ensures excellent lighting quality in prestigious areas such as lobbies and foyers or in common areas. In order to adjust the lighting situation to the individual needs of users, all three design sizes (940 mm, 640 mm and 440 mm) are now available with built-in tunableWhite technology. This means that ONDARIA's colour temperature can be continuously adjusted in the range between 3000 K and 6000 K.

With » MIREL evolution, Zumtobel is steering louvre luminaires towards modern times. By giving the luminaire a distinct appearance, Zumtobel has mastered the challenge of integrating energy-efficient LED technology into a tried-and-tested stylistic idiom: the lenses and the light source of MIREL evolution are visible to the user and are thus becoming a key design feature of the otherwise minimalist luminaire. Thanks to the particular shape of the lens, a directional beam pattern and a brilliant appearance are achieved without any annoying glare. Light distribution is effected via the lenses at a rate of 95 per cent; only 5 per cent of the luminous flux are reflected by the “louvre”. This results in more precise direction of light and higher luminous efficiency, which is also indicated by a luminaire efficiency factor of 112 lm/W. The luminaire's luminous flux levels and module sizes, however, have not changed as compared to the classic recessed luminaire. Conventional luminaires can be replaced on a one-to-one basis, which is a convincing argument in favour of using MIREL evolution in refurbishment projects.

The stylistic idiom of MIREL evolution featuring an opal optic has been reduced even further, so that the luminaire now appears as a flat, level luminous panel. For the version fitted with an opal cover, a 3Dprotect® reflector is used, which not only ensures perfect direction of light but also protects the sensitive LED modules during installation. Due to the interplay of innovative LED technology and direction of light in MIREL evolution fitted with an opal cover, a luminaire efficiency factor of up to 123 lm/W is possible.

With its clear, unobtrusive and universally applicable design, the luminaire developed by STUDIO AMBROZUS is able to exploit its full potential in terms of lighting quality and energy efficiency. With a colour rendering index of Ra > 80, the louvre luminaire is particularly suitable for the various visual tasks to be performed in offices. MIREL evolution is available as a recessed, lay-in and surface-mounted luminaire in a square or linear version.

In 2005, a new way of using the property from the seventies had to be found. It was generally agreed that not just another office complex would be built on this site, right in the heart of Zurich-West, a district that had meanwhile blossomed out into a cultural hotspot boasting the industrial charm of days gone by. Hence, based on a feasibility study, it was determined that the 24,435 m² Toni-Areal was to be transformed into the new central location of the » Zurich University of the Arts (ZHdK) and the » Zurich University of Applied Sciences (ZHAW) In the subsequently launched architectural competition, the project design submitted by the EM2N architects' studio came out first, and the building application filed in autumn 2007 laid the foundation for the ambitious renovation and new building project involving an investment volume of CHF 350 million.

Right on time for the start of the autumn term in September 2014, approx. 5000 students, lecturers and staff members could move to the new premises. In addition, not only 100 new flats including an accessible roof garden and a car park accommodating 240 cars, but also rooms for exhibitions, events and spaces for commercial use were created. A contemporary infrastructure was developed that not only allows interaction of various disciplines at one location, but also ensures the university's high educational and service quality as well as its international competitiveness.

The design of the campus building picks up the former industrial building's architecture, creating a heterogeneous space where different interests are reconciled, also in terms of lighting. The lighting concept toys with this heterogeneity. Its aim is not to produce uniform brightness, but to have the luminaires arranged so as to divide the space into zones and create a dialogue between light and dark. Also, the lighting solution is as capable of transformation as is the Toni-Areal site itself. On the one hand, ideal lighting conditions for learning and communication are produced; on the other hand, the creative ambience is enhanced and students are provided with the right light for their exhibition areas.

The key role in implementing this lighting solution is played by a modular luminaire system that meets the high demands in terms of flexibility and customisability: TECTON, which is able to fulfil complex functions and a variety of lighting tasks thanks to its versatility, compatibility and expandability within one system. The continuous-row lighting system is based on trunking incorporating an 11-pole current conducting section. All functions such as power supply, lighting control and connection to the emergency lighting system are integrated into this multi-functional trunking unit. In order to illuminate 1400 lecture rooms, seminar and training rooms, more than 33 kilometres of TECTON trunking were installed.

At peak times, more than 600 electricians were working on the construction site, installing more than 5500 TECTON continuous-row luminaires, among others. As required, a variety of optics and louvres were used, which can also easily be replaced or added if the requirements placed on the lighting solution should change.

In spring 2014, » Leica Camera AG moved to its new ultramodern manufacturing and administrative headquarters in Wetzlar, the town where the company was founded. Designed by Frankfurt-based architects » Gruber + Kleine-Kraneburg, the Leitz Park accommodates not only the Leica Camera AG complex, but also two other corporate buildings and a detached coffeehouse. Many areas of the new headquarters are publicly accessible, allowing visitors and customers insights into the history of Leica Camera AG and its products. Works by Leica photographers are presented here as well. In addition to the administrative headquarters, the complex also accommodates a museum, an art gallery, a Leica flagship store, a restaurant and manufacturing areas that are visible from outside. The individual building units are connected to each other on the ground floor, which is structurally emphasised by a surrounding glass façade that is curved in some places. At night, it keeps the building units together like a luminous ribbon reminiscent of a photographic film reel. With its clear stylistic idiom and unobtrusive design, the lighting solution implemented by Zumtobel in close coordination with the lighting designers from » hpi Himmen and » Lichtvision supports the self-confident yet discreet architectural structure of the Leitz Park, creating in every area an atmosphere in line with the user requirements of both visitors and staff.

The project involved the most varied specifications: first of all, the lighting solution was supposed to completely blend into the interior design, subtly enhancing the respective room's character. Besides, the requirements of various users had to be met. For instance, a perfect office environment was to be created for the staff working in the administrative complex. The areas open to the public required an inviting atmosphere to welcome visitors. In particular the art gallery made high demands on the luminaires' flexibility, since the exhibits on display in the temporary exhibitions shown here are constantly changing. An additional requirement specified by Leica was that it should be possible to control and dim all built-in luminaires via an EIB/KNX system integrated in the building management system.

For the headquarters' data centre, Zumtobel used CLARIS II pendant luminaires, which are characterised by reduced minimalism, linear design and a geometrical design language. Combined with innovative louvre technology, they provide for perfect lighting. In addition, the precise design of the groove of the indirect reflector ensures homogeneous illumination of the ceiling.

In secondary areas and corridors of the Leica building complex, » LINARIA surface-mounted luminaires facilitate spatial orientation. The clear lines of the batten luminaires provide gentle and uniform illumination, creating a room ambience that is perceived as very pleasant. Only three centimetres in height, the smallest of the DALI-compatible batten luminaires boasts an extremely complex design.

Two models of the » PANOS infinity LED luminaire range round off the lighting solution for the new Leica headquarters: they were installed as downlights in corridors and as wallwashers in customer areas and themed areas as well as in the coffeehouse. The mostly uniform colour temperature forms a visual bracket. While Zumtobel used downlights featuring a colour temperature of 3000 K for general lighting, the wallwashers required a colour temperature of 4000 K due to incident daylight. High functionality and flexibility was the decisive criterion for selecting the LED luminaires of the PANOS infinity range: “The Panos luminaires could not fail to impress us thanks to their quality, on the one hand: their high colour rendering, uniform light distribution and advanced LED technology allowed us to consistently meet the diverse requirements of the project. At the same time, the restrained stylistic idiom of the luminaire design enhances the building's architectural structures,” explains Isabel Sternkopf from Lichtvision. In addition, the wallwashers allow high-precision direction of light: the light is directed precisely where it is required by the exhibit or the application. The high energy efficiency of an LED solution, too, speaks for itself: by using LED luminaires, at least 40 percent of energy can be saved, as compared to a conventional luminaire system.

It is a truly Hollywood-style setting, and not just since the shooting of the James Bond movie “Quantum of Solace”. Situated in the immediate vicinity of the lake, Casino Bregenz opens up above the stairs to the summer terrace facing the Festival Square in the heart of Bregenz. Guests and passers-by are fascinated by the redesigned façade, which surrounds both the existing glazed front and the annex with metal sheeting.

From inside, guests enjoy an unhampered view of the lake, while the attention of passers-by is drawn towards the flowing, slightly irregularly arranged metal elements. When night falls, the façade is transformed into a shining interplay of colours, thanks to the CAPIX evolution LED media façade luminaire. As the individual CAPIX elements are linked by only one data line and one supply line, the 6500 single CAPIX pixels cling to the curved façade of the extended casino like a second skin. In total, the casino was fitted with 1140 meters of CAPIX. Since each CAPIX pixel incorporates three RGB LEDs, the lighting effect produced by CAPIX evolution is bright and brilliant even when viewed from long distances. In addition to generating colours and other effects, the control system of CAPIX evolution also allows running a sequence of moving pictures.

If required, the sequence of façade illumination can also be changed on short notice. At the same time, the new LED façade lighting also complies with the strict requirements regarding nature and bird protection applicable in Bregenz and features excellent energy efficiency. Within the scope of refurbishment, the interior was redesigned and extended as well, so that now the lounge is illuminated by brilliantly sparkling » DIAMO LED downlights that create a stylish ambience.

Together with the Festival House and the Floating Stage, the redesigned Casino Bregenz now forms a harmonious overall ensemble. The façade blends perfectly into the scenery and adds additional splendour to the cultural mile that has developed over the past years, ranging from the KUB Kunsthaus to the Landestheater and vorarlberg museum through to the Festival Square. For Casinos Austria, the media façade opens up new ways of presentation. Thus, not only guests but also passers-by can experience Casino Bregenz as an exciting work of lighting art at night.

On the occasion of its 150th anniversary, the Museum of Applied Arts/Contemporary Art (MAK) in Vienna has reorganised its permanent study collection, the » MAK Design Lab. In collaboration with the  » EOOS design studio and with curatorial advice from the » IDRV (Institute of Design Research Vienna), MAK Director Christoph Thun-Hohenstein has implemented a concept that helps visitors experience design as a central driving force for enhancing quality of life. Design that shows that sustainability today is not only a trend, but a necessity. EOOS' design for the new MAK Design Lab has proved once again that combining aesthetic appeal and environmental compatibility not necessarily requires bargaining to the least common factor. It is against this background that the lighting solution must be seen: a continuation of the long years of cooperation between EOOS and Zumtobel.

The design approach of EOOS is based on a clear commitment: to reduce the carbon footprint as much as possible. This principle is also reflected by the decision in favour of modular solid wood pedestals, the re-use of exhibition cabinets, and energy-efficient LED luminaires. Using carbon-binding wood as the predominant material has not only a positive impact on the carbon footprint, but also creates a warm ambience that invites visitors to stay and make discoveries for themselves. The lighting solution enhances this basic atmosphere, allowing visitors authentic insights into the multi-faceted universe of applied arts. In a floor space of 2000 square metres, some 300  » DISCUS evolution LED spotlights – instead of 100 halogen spotlights with poor efficiency – ensure individual presentation of approximately 2000 exhibits. Despite the threefold number of luminaires, energy consumption has been reduced by 32 per cent. Some of the spotlights are dimmable directly at the luminaire, 40 spotlights can be controlled via a DALI interface; both options have a positive impact on energy consumption and ensure sophisticated illumination of the various themed areas of the exhibition.

Not only the style of the MAK Design Lab sets new standards for environmentally compatible design; the content of the exhibition, too, aims at bringing about a new appreciation for craftsmanship and the long service life of products – hence, in the themed areas, visitors may embark on a journey through the past and future of design.

Thanks to its unmistakable look, which is characterised by the radial fins of its passive heat sink, the DISCUS spotlight seems to fit into the overall picture like an exhibit. Inspired by an ancient symbol of the sun, EOOS used all the potential of state-of-the-art LED technology for the design of the latest generation of DISCUS, implementing an even flatter design that minimises the carbon footprint. The replaceable optic extends the product's service life by making it flexibly adaptable to cope with new lighting tasks. Thanks to high-precision accent lighting, an excellent colour rendering index of Ra 92 and twice the luminous flux of its predecessors, the efficiency and effectiveness of the DISCUS evolution range is enhanced even further.

By combining state-of-the-art technology and intelligent design, EOOS and Zumtobel also managed to develop the innovative » ONLITE CROSSIGN escape sign luminaire. With a power input of no more than three watts and a light output ratio of over 100 lumens per watt, the highly efficient luminaire is more than qualified to provide emergency lighting in the museum. The emergency lighting system is monitored and supplied with power by the compact » ONLITE CENTRAL CPS central battery system that is based on a modular system and allows to provide a tailor-made solution, so that the relationship between functions and costs can be optimised in a consistent manner.

About the MAK
The MAK has always tried to bridge the conflicting priorities of traditions and the present. Founded in the 19th century as “Imperial-Royal Austrian Museum for Art and Industry” by Emperor Francis Joseph, it is today a museum showing art and the everyday world. In its various rooms, the museum situated on the Ringstrasse focuses on the future by confronting issues relevant to society with perspectives and approaches of contemporary art, applied arts, design and architecture, acting as a driving force that promotes a positive transformation of society, above all in social, environmental and cultural terms.

The “Hollein” exhibition will be on display at the MAK until 5 October 2014. Being Austria's only winner of the Pritzker prize and a designer in the most comprehensive sense of the word, Hans Hollein conveyed a new dimension to the term “architecture”. Plunging into his universe, the exhibition attempts a radical repositioning of his oeuvre based on material from Hans Hollein's archive, part of which has never been on public display before.

OMA, the international architects' studio based in Rotterdam, was commissioned with developing the design concept for the first “Maison Ullens” boutique in Paris. David Gianotten, one of OMA's partners, and project architect Inge Goudsmit worked in close collaboration with the founder of the label, Myriam Ullens. The result is a perfect mix of OMA's contemporary architectural style and the brand philosophy of Maison Ullens.

Although the boutique conveys unobtrusive elegance and restraint, the products are presented in a dramatic setting, also thanks to an ivory-coloured wall made of onyx marble that divides the store into two areas. In the spaces open to the public, the brand world of Maison Ullens is brought to life. Materials such as wood, marble, leather, brass and terrazzo are not only a reference to French history and craftsmanship, but also present subtle contrasts to the latest fashion designs. The changing rooms provide cocoon-like areas of retreat that create a warm and private atmosphere for customers to enjoy the shopping experience. In the entire boutique, PANOS infinity downlights and CARDAN LED  spotlights provide for uniform and pleasant LED ambient lighting. Here and there, accents are created by the modular MICROTOOLS lighting system.

The lighting solution supports this concept mainly through the lighting effect, while the luminaires themselves remain discreetly in the background. The minimalist yet powerful VIVO XS LED spotlight system has been installed on tracks in the ceiling and is particularly restrained thanks to its miniaturised design.  After all, the aim is to present the latest fashion items in the right light effectively and with unobtrusive elegance. Thanks to excellent colour rendering of Ra>90, the high-quality fabrics are set centre-stage authentically and gently by the LED-only lighting solution. However, the elegant materials used in the interior design, too, are enhanced to optimum effect by appropriate lighting. The SUPERSYSTEM E1 lighting system complements the lighting solution installed at Maison Ullens in Paris.

Safety in buildings is a matter of course. In a sphere so tightly controlled by legal standards, you would hardly think that there is room for individual design. In particular when it comes to application areas with increased safety standards or high ceilings, conventional lighting technology concepts soon reach their limits. Zumtobel's ONLITE RESCLITE high ceiling (HC) emergency luminaire is a powerful solution for high ceilings such as those mostly found in industrial bays, warehouses and shopping centres. RESCLITE HC can be installed in rooms with ceiling heights of up to 23 m (RESCLITE escape) or up to 30 m (RESCLITE antipanic) and offers all benefits of the classic RESCLITE luminaire range, such as virtually no maintenance, high energy efficiency and maximum spacing between luminaires thanks to optimised optics.

ONLITE RESCLITE HC is available in two models in compliance with EN 1838: as RESCLITE escape, for illuminating escape routes, and as RESCLITE antipanic, for room orientation in emergencies. The newly developed special lens of RESCLITE escape focusses the light along a lengthy, narrow strip. Thanks to high-performance LED modules and optimised optics, luminaire spacings of up to 22 metres can be achieved and the required minimum illuminance of one lux is ensured without any problems. Thus, energy-efficient illumination of escape routes in conformity with relevant standards is ensured.
On the other hand, antipanic lighting must achieve an illuminance level of at least 0.5 lux in order to provide orientation and allow people to safely find their way out of the building. Thanks to wide-angle and rotationally symmetrical light distribution, already one RESCLITE antipanic high ceiling luminaire is sufficient to uniformly illuminate an area of up to 290 square metres (at a mounting height of 16 m). With a high protection rating of IP65, the luminaires are protected against dust and water jets from any angle and hence also perfectly suited for use in harsh industrial environments. The luminaire can be installed directly on the ceiling or integrated into the TECTON continuous-row lighting system. It can be combined with the central CPS and eBox emergency lighting systems, which are available with DALI (NDA), Powerline (NSI) and circuit monitoring (NPS).

Additional support for emergency lighting designers
Zumtobel is also extending the services offered to emergency lighting designers. Not only is it possible to download the popular Zumtobel ONLITE RESCLITE app from the iTunes store, it is now also available on the Zumtobel website. Thus, access to the design tool is now possible from every PC, laptop, tablet or smartphone using any browser, independent of the device's operating system. On iPads and iPhones, the app can even be used offline and has become a valuable tool for emergency lighting designers. In just a few steps, the RESCLITE app is able to calculate the maximum spacing between emergency luminaires, depending on the mounting height.
Those who use mobile devices featuring different operating systems or laptops may download the tool from the Zumtobel homepage on the data sheet of every RESCLITE luminaire under the “Spacing” tab. There the mounting height of the luminaire can be adjusted by means of a slider. Subsequently, the maximum spacing between two luminaires is displayed.

The Biennale Architettura 2014 in Venice, curated by Rem Koolhaas, will open its doors on 07 June 2014. Until 23 November 2014, pioneering architectural ideas and concepts will be presented in the city with its lagoons and islands under the title of “fundamentals”. This year again, Zumtobel is involved as a sponsor, supporting two art projects by providing advice and lighting solutions developed specifically for this purpose. The Austrian lighting solutions provider has been a partner for central projects in the context of the most important exhibition of contemporary architecture since 2002.
“By supporting the Biennale di Venezia, Zumtobel makes a valuable and creative contribution to the discourse of light, architecture and art,” says Stefan von Terzi, Director Marketing at Zumtobel. “Our lighting solutions in the German Pavilion and the Central Pavilion also show how important it is to provide the right light for the installations and the architecture to present them to optimum effect.”

Fast motion presentation using LED
Koolhaas' motto of the exhibition in the Central Pavilion is “Elements of Architecture”, putting the focus on the fundamental components of a building such as the ceiling and the stairs. In order to enhance the experience and encourage discussion, Zumtobel has developed and implemented an integral lighting concept for the impressive domed area located at the centre of the pavilion. The main feature is a special LED solution that sets the ceiling fresco by the Italian painter Galileo Chini in the dome centre stage using various colour temperatures (TunableWhite technology). The installation, which is concealed behind a sill and integrated in a suspended ceiling at the same time, simulates the natural course of daylight. By means of various colour temperatures ranging from warm (3000K) to cool (7000K), the ceiling fresco is provided with fascinating aesthetic qualities, highlighting the polarity between nature and built-up space .

Zumtobel sets the stage for architecture installation in German Pavilion
For the exhibitions of the 29 National Pavilions at the Biennale, Koolhaas has made “Absorbing Modernity: 1914-2014” the overriding theme and has requested the countries to revert to their national architecture of the past 100 years. This year's curators of the German Pavilion, the Swiss-based German architects Alex Lehnerer and Savvas Ciriacidis, have responded to this request through an accessible room-to-room installation called “BUNGALOW GERMANIA”. This is an architectural assembly of two buildings historically significant to Germans: the first is the German Pavilion in Venice itself, built in 1912, converted in 1938 and 1964. The second building is the Chancellor's Bungalow in Bonn by Sep Ruf, built in 1964. These two buildings represent two eras in German history, two political systems and two architectural idioms.
The installation by architects Lehnerer and Ciriacidis is a 1:1 replica of parts of the Bungalow integrating the architecture of the Pavilion. A “third room” is eventually created that links the histories, moments, eras and locations of the two buildings, allowing for new associations in terms of form and use of architecture and the related German history. The unique architecture of this project is enhanced by a special lighting solution provided by Zumtobel, strongly emphasising the concept of the two artists.

The new flagship store of the Spar retail chain situated at Budapest's “MOM-Park” is a market hall with a sophisticated architectural design where the emphasis is to provide customers with a unique shopping experience. With this goal in mind, the Budapest-based architects' studio LAB5 developed a wave-shaped wooden ceiling structure for the 2000 m² supermarket that merges with the wall shelving, accentuating the spacious open-plan room structure. The wood creates a pleasant natural atmosphere that makes customers feel at ease. The store layout is characterised by free-standing retail islands and counters, where customers can explore the goods displayed and obtain advice. The walkways have been designed so that customers who are in a hurry can proceed directly to the POS terminals via so-called “to-go counters” situated at the entrance. In addition, large counters manned by sales staff are situated along an extended route through the market for shoppers who are willing spend more time. The aim of this concept is to increase customer satisfaction. A significant part of the unique shopping experience in the Spar flagship store is due to the lighting, which not only sets the stage for optimum presentation of the goods, but also creates an inviting ambience that makes customers stay and feel at ease. In close coordination with the architects, Zumtobel has implemented an efficient LED lighting solution that completely blends into the interior and ensures optimum presentation of the products using accent lighting.

Visual highlighting of individual product groups ensures attractive product presentation and makes it easier for shoppers to find their way within the store. Moreover, the freshness of the food displayed is emphasised by targeted use of specific colour spectrums. For illuminating the fresh food department and the wine racks, Zumtobel has opted for efficient high-performance LED spotlights: swivelling VIVO LED “Tunable Food” spotlights and CARDAN “Tunable Food” recessed luminaires provide high-precision accent lighting in order to present sensitive foodstuffs such as meat and fish to optimum effect. Zumtobel's “Tunable Food” LED concept allows product-specific illumination and effective presentation of goods. Thanks to innovative technology, the perfect colour temperature can be adjusted directly at the spotlight, with ten colour settings already pre-programmed. This ensures an authentic look of the products with perfectly uniform light distribution. Furthermore, IR- and UV-free lighting provided by LED luminaires is gentle on fresh food and reduces harmful thermal output, ensuing that fruit and vegetables remain luscious and meats stay fresh longer.

Baked goods, the wines on offer and the cheese counter are presented to optimum effect by the VIVO LED and CARDAN LED spotlights featuring built-in “Stable White” technology in a colour temperature of 3000 K. The market hall's uniform ambient lighting is provided by TECTON, a flexible continuous-row LED system integrating batten luminaires, light sources and reflectors within its trunking. This allows for easy installation and reduces maintenance costs. TECTON has been mainly installed as individual light ribbons in the wooden ceiling and between the shelves, which allows the luminaires to blend decoratively into the interior, underlining the character of the room.

Another benefit of the LED lighting solution fitted at the Spar market in Budapest is its high energy-saving potential. By using LED luminaires, at least 40 percent of energy can be saved, as compared to a conventional luminaire system. In addition, LED luminaires by Zumtobel boast a service life of at least 50,000 hours – the LED lighting solution therefore requires virtually no maintenance.

Computer-aided research and studies on hot engines: the perfect solution to the problem of combining these two different task areas under one roof has been provided by the Cologne-based architects Lepel & Lepel for the “Center for Mobile Propulsion” of RWTH Aachen. The building complex includes a seminar and administration building as well as a test rig hall for engines. Here, engineers and scientists study the theory and practice of new propulsion technologies and optimised performance of engines for passenger cars and utility vehicles. Both buildings serve the same purpose of research, but have different functions – which is also reflected by their architecture: the seminar and administration building has an open and inviting feel with its curved form and soft lines, featuring glazed panels and flexible room layouts inside. In contrast, the test rig hall has been designed as a closed, solid structure made of dark exposed concrete with narrow windows and ventilation slits. Here the engines are tested in compliance with high safety standards and strict technical requirements out of the public eye. Although the two buildings stand in stark contrast in terms of design, they complement each other subtly in terms of functions. The waste heat produced during the engine test runs, for instance, is used for heating the seminar building. The construction's sustainability is also demonstrated by the high levels of daylight available in both buildings, which allows for predominantly natural lighting of the working environment, enhances the staff's sense of well-being and saves energy costs.

In order to provide supplementary illumination with artificial lighting, the Cologne-based architects and the lighting designers of a•g Licht from Bonn developed an individual solution for each building. According to the requirements, perfect task lighting with high lighting quality had to be ensured. At the same time, the lighting and the architecture had to form a harmonious ensemble. Zumtobel was responsible for implementing the concept and managed to win the customer over thanks to the company's international experience, premium advisory skills and wide range of products.

In the foyer of the administration building, the lighting solution expert has installed LINARIA decorative luminaires. They provide ideal lighting conditions to facilitate orientation and guidance and enhance the room's architecture thanks to their extremely slim design. In the offices and seminar rooms, Zumtobel has fitted 420 ECOOS luminaires arranged in continuous rows. The individual luminaires have been positioned one after the other to form narrow light lines without any visible fittings or connectors. Thanks to direct, indirect and lateral light components, ECOOS ensures efficient lighting for the workstations and also provides vertical illumination. This improves the staff's visual comfort and concentration while bright ceilings and walls create a pleasant room atmosphere. ECOOS also allows for quick and easy installation. In this way, the lighting system can be smoothly adjusted to new room layouts. “ECOOS could not fail to impress us thanks to its high flexibility, minimalist design, brilliant optic and extremely large direct/indirect light component,” says architect Reinhard Lepel. “In addition, the luminaire boasts lower operating costs than other luminaires, so that the investment will pay for itself within a short period.”

In the engine test rig hall, the efficient TECTON continuous-row lighting system meets all require-ments placed on optimum lighting of workstations and perfect orientation even from large heights. Some 400 TECTON luminaires have been installed in this area. They can be positioned flexibly, and the system can be adjusted to changes in room layout at any time. TECTON is a continuous row system mounted on trunking that incorporates all luminaire modules and a current conducting section. Only the lighting modules, light sources or optics are replaced or added, if required. This allows quick expansion and adjustment of the lighting solution and reduces installation times and maintenance costs. This is a major asset especially in those areas of the hall that are difficult to access.

Cornea Ti – morphing light to space
Cornea Ti, the lighting installation created by students of the bachelor degree programme in interior design at the University of Applied Sciences in Mainz, will be located on a container boat near Untermainbrücke. In a world of data encryption and encoding, the installation visualises illusion and reality of a message, creating a bridge into our information age.

At twilight, 1600 video-compatible Capix LED façade luminaires by Zumtobel turn the installation to life, ensuring an interactive spatial experience for visitors. The secret of Cornea Ti is an anagram – a new word is produced by rearranging its letters. While visitors walk through the installation, the transformed letters will produce a word the real meaning of which has to be deciphered.

In the process, the LED pixels are individually controlled in real time via a PC and animated as a system responding to movement in the space. In this way, visitors are accompanied by interactive light on their way through a world of letters, creating a personal experience of space. The lighting installation is accompanied by music. Every night, live concerts will be held in collaboration with musicians from HfMDK Frankfurt and Ensemble Modern, indulging visitors in a unique light and sound installation.

Twinkle Twinkle
A second installation sponsored by Zumtobel can be found on the square in front of the Deutsche Bank Towers. Consisting of 576 prism poles made of glass, the Twinkle Twinkle installation is a transparent and dynamic structure that reflects daylight and its surroundings, creating an enthralling experience for visitors. Daylight is refracted by the prism poles, which produce lighting-like reflections fanning out into a fascinating colour spectrum.
In daylight, the sculpture appears scarcely palpable; at night, 18 Elevo RGB DMX façade luminaires set the four-metre concentric structure aglow. The special lighting presentation creates a dramatic effect, which is enhanced by background music.  Twinkle Twinkle is a project by Glasbau-Hahn GmbH, NE-AR Nixdorff Etchegorry – Architecture Research, lichtundsoehne – lighting & visual design, O-S-D – office for structural design and studioheyhey – visual communication.

At this year's light+building, Zumtobel – as an expert in the field of interior lighting for commercial purposes – will also present an extensive product range for façade & architecture applications.

Zumtobel. The Light.

• 82.5% of those surveyed prefer direct/indirect lighting

• 60% of office employees prefer illuminance in excess of 800 lx, this preference becoming less marked with increasing age

• Even in summer months, the need for artificial lighting is high

• 57.4% of those surveyed have no or only limited ability to influence their lighting situation in order to adjust it to their needs

• Colour temperature preferences differ widely, ranging from 3000 to 6000 K, with a significant cluster around 4000 and 5000 K

• 2,643 participants from Europe, Asia, Australia and the USA have been participating in the study since November

Numerous directives, standards and assessment criteria have to be taken into account when designing lighting solutions for office workstations. Other important factors include individual user preferences, task-related requirements and employees' emotional well-being. In order to throw light on all these aspects, Zumtobel, together with the Fraunhofer Institute for Industrial Engineering (IAO), has developed and conducted a long-term study on a global scale: under the title "The Light. Global User Study on Lighting Quality Perceived in Offices"*  , 2,643** office employees from Europe have already assessed the lighting situation in their personal work environment with the aid of a multilingual online survey form since November 2013. The aim of this long-term study, which will run until the end of 2014, is to allow as many different users as possible to assess perceived and expected lighting quality in a variety of office situations.
This is creating a highly informative, global map of light that will provide information indicating which settings are best suited to particular individuals in specific situations. Zumtobel will use the study findings to build this knowledge of user preferences and behaviour into its product development work. LIGHT FIELDS evolution tunableWhite and SEQUENCE are direct fruits of this user-focused process. It is making it possible to anticipate what innovative lighting solutions will have to be able to do for employees in offices in the future. According to Fraunhofer IAO data, this Zumtobel study is already one of the most successful ever investigations of this topic in terms of the numbers of users who have participated in it. The fact that over 60% of those surveyed state that they want to be informed of the research findings shows how interested users are in this subject. 

Office employees prefer direct/indirect light and high illuminance
One of the most important interim results is the clear preference expressed by study participants for direct/indirect lighting and illuminance higher than that specified in the relevant standard. 61.6% of those surveyed only have direct or indirect lighting in their office, a situation that is preferred by only 17.5% of them. In contrast, 82.5% of those surveyed prefer direct/indirect lighting. Most users also prefer lighting can be flexibly adjusted to suit various tasks.

The study is also yielding the first noteworthy findings indicating clear preferences when it comes to illuminance: 500 and 800 lx in the task area are perceived as being the most pleasant illuminance levels. About 60% of those surveyed nevertheless expressly want illuminance levels higher than 800 lx – a level significantly higher than the mandatory 500 lx stipulated in the relevant legal standard.

Strong demand for individually adjustable artificial lighting
Participants' preferences regarding colour temperature have provided an interesting interim result: across all age groups, genders and nationalities, it was established that user preferences when it comes to colour temperature range from 3000 K to 6000 K, with a clearly marked majority preference for 4000 K and 5000 K scenarios. Continuously colour-temperature adjustable LED luminaires cater for these individual needs the most effectively. After more in-depth analysis it is also striking that there is also relatively high demand for artificial lighting in summer, not just in dark winter months. 60% of those surveyed use more than seven hours of artificial lighting in winter, and 33% still use this much artificial lighting even in summer. One reason for this might be the fact that 61.2% of those surveyed do not sit in the vicinity of a window and therefore enjoy relatively little natural light. This makes it clear how great the need for artificial lighting is, and emphasises how important it is to coordinate daylight and artificial lighting. It also makes the size of the comparative potential energy savings that can be achieved by using an intelligent, daylight-based LED lighting solution quite clear. The study has also shown that 57.4% of those surveyed, i.e. more than half, have no or only limited ability to influence their lighting situation in order to adjust it to their needs.

Analysis of these interim results makes it obvious that innovative lighting solutions for office environments must be controllable in a differentiated, intelligent and individual manner. This way, lighting can be adjusted straightforwardly to meet requirements in any task area in order to deliver the right light for each visual task and every situation. Combined with daylight, an intelligent lighting solution therefore promotes both employees' well-being and health. And it also makes a considerable contribution to energy efficiency. "This study is giving us a differentiated picture of modern office architecture and the needs of employees in businesses all over the world" says Christoph Mathis, Director of Global Application and Product Management. "The results will be fed into our product development work worldwide and really help us achieve our goal, the best light for people and the environment."

This monitoring tool is perfectly matched to lighting management systems such as LITECOM; it monitors energy consumption within a company and shows how to achieve optimum energy efficiency using lighting management. Buildings, floor levels, rooms or even individual workstations can be addressed and conveniently presented in sunburst diagrams, so that their energy consumption can be optimised.

Zumtobel. The Light.

The most recent study carried out by Zumtobel Research in the field of user research is dedicated to the subject of individual user preferences for  the lighting of workstations. In the user study developed together with Fraunhofer IAO  it was soon found that most office workers want more influence on the lighting situation, and that they prefer a combination of direct and indirect light. This fundamental application knowledge forms the basis of Zumtobel's user-oriented design process. On the basis of these research findings, Zumtobel has adjusted and extended its product range for office applications.

SEQUENCE – LED luminaire for adaptable lighting at the workstation
With SEQUENCE, Zumtobel launches an LED luminaire in the market that meets the manifold requirements of employees with respect to ideal office lighting as well as the need for individuality to the utmost degree. SEQUENCE offers a perfect combination of direct and indirect lighting and scores high on modules than can be individually controlled. SEQUENCE has been designed as a pendant or surface-mounted luminaire and consists of 8 or, optionally, 14 module units arranged alongside each other, each with 6 x 3 centrally arranged LED light points. The special lens technology in front of each of the 18 central LEDs provides for optimal direction of the task light with simultaneously high glare control, thus preventing annoying reflections on displays. This requires an optical system explicitly matched to LED technology:  the transparent lenses ensure a high light output ratio of the system, and accordingly a luminaire efficiency of up to 100 lm/W with a luminous flux level of up to 9000 lm, by reflecting the injected light. At the same time, thanks to an opal cover frame, the 24 outer LEDs provide diffuse ambient light as well as an altogether softer light distribution. Grouped together in three sets, the individual modules and the indirect light component can be controlled individually. Each set has a DALI address. The electronic control system, especially developed for SEQUENCE, ensures gentle transitions between the 14 modules. This makes adaptive lighting possible. Besides this exceptional performance feature, SEQUENCE boasts an especially slender design that blends perfectly into any interior. SEQUENCE is available with colour temperatures of 3000 K (warm) and 4000 K (intermediate).

LIGHT FIELDS evolution TW – LED luminaire range featuring Tunable White technology
The LIGHT FIELDS evolution Tunable White LED luminaire range complies with the clear and uniform stylistic idiom of the iF design award-winning product range, steering it towards a user-friendly future thanks to profound application know-how and technological innovations. LIGHT FIELDS evolution featuring Tunable White technology is Zumtobel's answer to the users' need, as shown in the course of a Fraunhofer study, for adaptive light that can be customised. Tunable White stands for intelligent adjustment of the colour temperature to changing room situations and room utilisation. The whole luminaire range can be continuously dimmed by the user between warm (3000 K) and cool (6000 K) colour temperatures, allowing for implementation of a perfect lighting situation at the workstation. This is made possible by integrating Tridonic Tunable White LED modules together with a matching converter. Tunable White also allows for adjustment to changes due to the time of day and the season: depending on requirements, the luminaire can be adjusted to match the currently prevailing conditions. At the same time, LIGHT FIELDS evolution Tunable White offers perfect lighting quality without glare, just like the rest of the LED luminaire range. This is made possible by the patented micro-pyramidal optic (MPO+) that prevents annoying reflections on displays. Even at high luminous flux levels, luminance is consistently reduced, providing pleasantly distributed light. In addition, innovative technologies have been incorporated in the various luminaire models. For the recessed, surface-mounted and wall-mounted luminaires, Zumtobel has developed the 3Dprotect® reflector. Its 3D structure protects the LED modules during installation, preventing damage from electrostatic discharge. At the same time, the structure's high reflection factor ensures an increase in the luminaire efficiency level. In the free-standing and pendant luminaires, the dot matrix based on the litePrint® light guide technology ensures uniform light distribution. At the same time, a precisely defined light component is directed upwards in selected areas, via openings in the luminaire housing.

PANOS evolution and PANOS infinity – extended LED downlight ranges
Thanks to excellent lighting quality, high-quality materials, an unclutterd design and innovative technologies, the PANOS range is one of the most efficient and comprehensive LED downlight ranges in the Zumtobel product portfolio. The new PANOS evolution LED range combines the familiar benefits of the PANOS family with efficient high-output LED modules featuring a colour rendering index of Ra > 80. The new range is available in a round and a square version. Additionally, customers may choose from three lumen packages of 1000, 1800 or 2400 lm, with alternative colour temperatures of 3000 K or 4000 K. Moreover, the successful PANOS infinity and PANOS evolution ranges are extended to form a global range, and are specified for different markets all over the world. In a first stage, both round and square versions of the downlights are available in various colour temperatures of 2700 K to 4000 K.

AXON – direct/indirect pendant LED luminaire
With a cross-section of 38 mm x 38 mm, the slimline AXON pendant luminaire is designed for contemporary office architecture, and it also impresses through excellent lighting quality. Thanks to the combination of high-output LEDs and the latest LED lens technology, the light is optimally directed and at the same time perfectly glare-free. Additionally, the perfect balance between indirect and direct light distribution provides for a pleasant atmosphere at the workstation. For individual adjustment to user requirements, AXON is available in different versions and with a colour temperature of either 3000 K or 4000 K.

SFERA – free-standing LED luminaire featuring swarmControl technology
Open-plan layouts are common in today's offices. The SFERA free-standing luminaire supports individual visual needs of employees in an office environment and enhances a sense of well-being at the workplace with a high luminous flux level of over 11,500 lm and innovative technologies. This includes the sensControl presence detector that switches the luminaire on or off depending on whether anyone is present at the workstation. A brightness sensor additionally measures illuminance on the desk and dims the luminaire according to the ambient lighting conditions. Additionally, innovative swarmControl technology allows for quick and simple adjustment to changing room situations, by means of the corridor function and presence detection. The former primarily provides for safety and orientation: by means of a presence detector the luminaires are dimmed up one after the other, indicating the way to the workstation. The presence-based function, on the other hand, ensures ideal lighting conditions at the workplace, with the light quantity being adjustable at any time. SFERA communicates with neighbouring luminaires and forms a light cloud around the workstation.

Zumtobel. The Light.

Modified forms of collaboration, conventionally desk-based, in project teams or in open plan offices: nowadays people demand differentiated lighting solutions that are capable of adjusting to their needs and the tasks in hand. The technology of the Sequence pendant and surface-mounted LED luminaire meets precisely these user needs. Developed from scratch – not just its design, but also all its electronic and control systems – this luminaire exploits the capabilities of modern LED technology to the full.

Sequence has been designed as a pendant or surface-mounted luminaire and consists of 8 or, optionally, 14 side-by-side module units of identical design, each with 6 x 3 centrally located LED lighting points. Special lens technology with symmetrical or asymmetrical distribution characteris-tics in front of each of the 18 central LEDs ensures perfectly directed task lighting with good glare control. This prevents annoying reflections on screens, tablets or smartphones. At the same time, thanks to an opal cover frame, the 24 outer LEDs provide diffuse ambient light and altogether softer light distribution.

Individually controllable modules
Grouped together in three logical sets (each consisting of 4 outer modules and 6 inner modules), the individual modules, as well as the indirect light component, are individually controllable. Each set has a DALI address. The electronic control system, specially developed for Sequence, ensures gentle transitions between modules, despite the fact that there are only four addresses for 14 mod-ules. This makes adaptive lighting possible.

Besides this exceptional performance feature, Sequence, thanks to its flat aluminium housing, boasts an especially slim shape that blends perfectly into any interior design. The luminaire's so-phisticated design – all its electronic components are almost invisibly enclosed in a slightly raised area on the top of the luminaire unit – ensures a delicate appearance.

Sequence is available with a colour temperature of 3000 K (warm) and 4000 K (intermediate). Zumtobel supplies this luminaire in lengths of 1200 mm (6 LED modules) or 2100 mm (14 LED modules).

Zumtobel. The Light.

Contemporary office environments feature flexible workstation design and are based on the individual needs of office users. Team workstations, conference islands, tablet or PC work: for a wide range of applications, users need not only ideal lighting conditions but also a lighting system that can be adjusted to meet their specific needs. Tunable White stands for intelligent adjustment of colour temperature to changing room situations and room utilisation. The whole luminaire range can be continuously dimmed by the user between warm white (3000 K) and cool (6000 K) colour temperatures, allowing to implement a perfect lighting situation at the workstation. This is made possible by integrating special Tridonic Tunable White LED modules together with a matching converter.

Tunable White also allows for adjustment to changes based on the time of day and the season: depending on requirements, the luminaire can be adjusted to match the currently prevailing conditions. By adding Tunable White technology to the luminaire range, Zumtobel now offers a customisable lighting solution that can be adjusted to personal preferences and tasks and at the same time reduces complexity for the designers.


Innovative technology providing perfect lighting quality
No matter whether you work at a computer, use a tablet, attend a meeting or hold a presentation: the LED luminaire range will always provide perfect lighting quality without producing any glare. This is made possible by the patented micro-pyramidal optic (MPO+). The diffuser layer of the optic uniformly resolves the LED points, preventing annoying reflections on displays. Even at high luminous flux levels, luminance is consistently reduced, providing pleasantly distributed light even at steep radiation angles.

In addition, innovative technologies have been incorporated in the various luminaire models. For the recessed, surface-mounted and wall-mounted luminaires, Zumtobel has developed the 3Dprotect^® reflector. Its 3D structure protects the LED modules during installation, preventing damage from electrostatic discharge. At the same time, the structure's reflection factor ensures an increase in the luminaire efficiency level. In the free-standing and pendant luminaires, the dot matrix based on litePrint^® light guide technology ensures uniform light distribution.

Award-winning design
The Light Fields evolution LED luminaire range combines a clear stylistic idiom with technological innovation. Thanks to their uniformly slim-line design, low mounting height and high-grade, light-weight materials, the luminaires blend perfectly into contemporary office interiors. For these features, the LED luminaire range has won the iF product design award 2014.

Zumtobel. The Light. 

The long-established Reform Club is situated in the heart of London`s Clubland. Its founders commissioned Sir Charles Barry, at the time one of the most renowned architects, to design an ‘imposing and Palatial Clubhouse’ which opened in 1841. The original decorative finish of the Victorian-age building has been undergoing delicate conservation and restoration and it is considered one of the most important “Grade 1 historic listed interiors in London. From the outset, a clear client vision and concept was to introduce life back into the Grand Hall, with its galleried landings and wonderful Atrium. The lighting was to be ‘The Eyes’ through which to enjoy this internationally important Grade 1 listed historic interior, providing a soft warm three dimensional glow bringing architectural details, artworks and paintings to life.

The Bristol-based “Lighting Services” worked closely with the client to deliver a lighting solution which has received acclaim "English Heritage is delighted with the scholarly programme of restoration and conservation work at the Reform and considers that its outstanding interiors are greatly enhanced by the lighting scheme adopted". Zumtobel was chosen as the appropriate partner to provide the concept led technologically advanced lighting and control systems. Product design fulfilled the requirements in terms of efficiency, sustainability and flexibility which played a role in delivering the final outcome.

Based on Zumtobel`s intelligent Luxmate Litenet lighting management system, ‘Lighting Services’ were able to develop an innovative lighting concept that provided adaptable multiple DALI LED spotlights which cross washed 18 listed portraits and once dark and out of sight, the splendid coffered ceilings, swags and pilaster capitals are now vibrant and alive. The columns are set in relief providing a wonderful overall balanced visual effect to what is in essence a fabulous stage set. Thanks to the system's compatibility, the lighting solution can be adjusted as required and can also be extended to incorporate other areas and fittings.

Daylight-based control increases comfort and efficiency
Since the building is used 24/7, potential energy savings had to be identified and realised to optimum extent. This sustainable lighting solution is based on the perfect interplay of state-of-the-art LED technology and innovative luminaires with intelligent lighting management as its centrepiece: the Luxmate Litenet lighting management system combines complex system features such as use of daylight, presence detection, integration of emergency lighting, and predefined room profiles in one central unit that is easy to operate. The external daylight sensor installed on the roof continuously monitors incoming daylight, thus optimising the use of daylight. In every room, just the quantity of artificial light is added that is required to achieve optimum lighting conditions.
In addition, Luxmate Litenet provides a high degree of flexibility, which was the decisive factor for its use at the Reform Club. As the lighting system will be refurbished step by step in other areas and rooms as well, the client requires the system to be easily extendable in the future. Using pre-programmed scenarios, Luxmate Litenet also provides the opportunity to easily and conveniently create appropriate atmospheres for a variety of social gatherings and other events in the areas designated for this purpose.

As the heritage requirements dictated that the light source should not be visible for the most part, the minimalist Supersystem LED lighting system was used in all areas, both on the ground floor and the first floor. Thanks to its pared-down design, Supersystem blends unobtrusively into the architecture, enhancing it to optimum effect. The high-power LED spots cannot fail to impress on account of their modularity, since lighting inserts for direct and indirect lighting can be flexibly placed next to each other within one module, which allows them to tackle a variety of different lighting tasks easily. In the atrium, the lighting solution is complemented by DALI LED Decoline and Discus LED spotlights. They set the lighting stage for the impressive “sun-burner”, an oversized historic gas lantern formerly used for illumination and heating.

With the lighting required – both by the Client’s concept and heritage constraints – to be in relatively inaccessible locations the life and location of components and the cost of their maintenance and component replacement was a key factor. The traditional lighting had required a visual manual check on failed bulbs and their regular and frequent replacement.

About the Reform Club
The impetus for the establishment of the Reform Club was the Great Reform Act of 1932. The Club is in the heart of London’s Clubland. Established in 1836 by the Whigs and the Radicals the club later became the home of the Liberal party.  It is now without any affiliations to any political party. The Club is well respected worldwide and is at the hub of an international membership and provides a significant and varied intellectually challenging programme. The link with the past enhanced by the magnificent architecture of Sir Charles Barry provides a brilliant and inspiring stage set in which to host the intellectual and social life of the Club.

Zumtobel. The Light.

Milan Cathedral is one of Europe's most famous churches in terms of architecture. The Museum of the Cathedral is located inside the Palazzo Reale and recounts the cathedral's history –even before the laying of the first stone in 1386 to the present day. With a view to Expo 2015, and in order to make the extensive collection comprising valuable sculptures, paintings, church windows and scale models of the cathedral accessible in their full complexity, the museum had been closed for refurbishment for a few years. November 2013 saw the reopening of the exhibition, which has been allocated more space and is now presented in a new light.

Visitors will embark on an exciting journey through time on a floor space of some 2,200 sqm, divided into 27 large rooms and grouped into 13 thematic areas. By providing a lighting solution that boasts an unobtrusive design language and can be precisely adjusted to any situation, Zumtobel has set the course for allowing visitors an authentic experience and glare-free exploration of the exhibits. The exhibition centres upon the scale models of Milan Cathedral made from a variety of materials such as plaster, bronze and wood, the largest – and also oldest – among them a walk-in model made of wood, built at a scale of 1:20. The historic model originating from 1519 is made alive by an interplay of light and shadow imitating natural sunlight.

The well-devised lighting concept is based above all on highly efficient Arcos Xpert LED spotlights. As the colour temperature can be selected directly on the spotlight and replaceable optics can be individually adjusted, they provide the versatility and flexibility required by the exhibits' different materials. In order to enhance the sculptures' three-dimensionality and avoid hard shadows, soft outline lenses and accent lighting directed from various positions were used, accompanied by an excellent colour rendering index of Ra 94 as well as UV-free and IR-free LED light that is gentle on the exhibits. Moreover, the luminaires recede into the background thanks to their purist design, yielding the stage to the exhibits.

While the exhibits in the exhibition rooms are mainly illuminated by Arcos Xpert spotlights, highly efficient Panos Infinity LED downlights as well as the Tecton continuous-row lighting system and Linaria light lines are used in the side rooms. The Veneranda Fabbrica (Venerable Factory) was established more than 600 years ago to supervise the construction of Milan Cathedral. Today, the organisation deals mainly with maintenance, preservation and restoration of the church. One of its well-kept treasures is the Archive situated in the building opposite the cathedral, in Piazza Duomo 20, displaying more than 500,000 historical testimonies and documents dating back as far as to the year 1145. Perluce recessed luminaires ensure gentle illumination of photosensitive documents while at the same time providing ideal lighting conditions for the staff's work.

Thanks to this interplay of flexibility and lighting quality, taking conservational aspects into account as well as ensuring high energy efficiency, the lighting solution could not fail to impress both clients and architects. In the course of intensive design work and based on several models, they managed to jointly develop an individual lighting concept resulting in fascinating brilliance.

About the Museo del Duomo:
The Cathedral of Milan is the principal landmark of the city and one of the most important buildings in the world. From the beginning of its construction, the Veneranda Fabbrica has kept watch over the cathedral and collected valuable historical testimonies. The new museum and the refurbished archive are true treasure troves that not only allow insights into the cathedral's history spanning more than six centuries, but also take visitors to an exciting journey through Milan's past. For a visit to become an authentic experience, architects and designers have relied on visual and haptic design elements to make all dimensions of the Cathedral as well as its fascinating history come alive.
