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 archi-tects' 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 dis-played 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 flexi-ble 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.

Nature as Inspiration
To capture the Provence lifestyle and nature with all its aromas and colours in an authentic manner was one of the essential goals from the very beginnings of the cosmetic manufacturer L’Occitane en Provence. This is reflected for example in the perfumes and cosmetic articles packaged in simple jars and tubes, and also in the boutiques operated in more than 100 countries, inviting shoppers on a “journey into nature and the region of southern France”.
At the new boutique in the Carrousel du Louvre in Paris this journey begins in the underground shopping mall planned by Ieoh Ming Pei, which became famous through an upside down glass pyramid. In contrast to the rather cool elegance of the passage, customers are awaited behind the large display window by a kind of provincial market with traditional wooden furniture, dark parquet floors, small ceramic tiles and woven shopping baskets. Another characteristic feature is the ubiquitous use of ochre hues – reminiscent of the cliffs of the Luberon mountains and the special light of the Provence – as well as a translucent backlit glass roof, creating the impression of warm sunlight falling into the interior.
Both to support the extremely cultivated atmosphere and in the interest of a flexible light solution that is suitable for pleasant general lighting and specific accent lighting, the clients and planners chose a total of 70 IYON LED spotlights with a uniform warm white colour temperature (3,000 K). Mounted on tracks, the spotlights are positioned in the display window, as well as below and on the gallery – some as spots and some as “wideflood” versions with wide beam optics. The decision for this light solution, which includes 16 PANOS INFINITY LED surface-mounted luminaires for illumination of the checkout area, resulted from the high colour rendering (Ra 90) and the high energy efficiency, which not only saves money, but also reflects the commitment to nature and the environment at L’Occitane.

The multi-functionality of the building and its open, light-flooded architecture created special lighting requirements. That is why architect Peter Zumthor placed special emphasis during the planning stage on a flexible lighting solution that enhanced the architecture of the house with no compromise in the quality of light. In addition, the lighting scheme had to create a pleasant atmosphere for visitors and employees.
In cooperation with Zumtobel, a customised light concept was developed with numerous special solutions. The exhibit area exclusively features state-of-the-art LED technology with easy connection to a lighting management system. This solution allows flexible control of the illumination during events and exhibits. For perfect room acoustics a panelled wooden ceiling with thick padding was installed in the open hall of the building. By means of a specially designed suspension system Zumtobel positioned 160 LED spots from the PANOS INFINITY series here. The downlights feature homogeneous basic illumination, excellent light quality and maximum efficiency.
Almost 90 VIVO swivelling LED spotlights provide for accentuated light and outstanding colour rendering, especially for highlighting single exhibit items. The TECTON continuous row lighting system ensures easy connection to the power supply and the lighting control system, as well as integration of emergency lighting. Thanks to tool-free installation, the system allows fast adaptation of the light solution to changing requirements.

The store not only has a unique design concept, with a brand signature created exclusively by British children’s book illustrator Polly Dunbar, but also a bespoke lighting solution from Zumtobel. The client required a lighting concept that complemented the Katakeet image and created an emotional shopping experience for the customers, young and old. While IYON, the modular CARDAN spotlights and SUPERSYSTEM spots illuminate the exquisite designer collections, PANOS INFINITY and MICROS LED downlights provide the right general lighting to emphasise the playful yet sophisticated atmosphere. The store in the Mall of the Emirates has been constructed with ecologically sensitive materials and finished with special emphasis on energy conservation and customer comfort.
"Zumtobel Lighting provided excellent support in realising this unique fairyland for children and their parents,” resumes Linton Crockford-Moore, Creative Director, Creative Eye Strategy & Innovation Chalhoub Group.

The two upper, closed levels of the hall are offset in relation to each other, so they are perceived as separate units that divide the massive structure visually into smaller parts. This impression is enhanced by a delicate, interlaced aluminium façade. In contrast to the bright outward appearance, the exhibition halls themselves have no windows. The dark supporting structure is unobtrusive and offers a neutral background for the impressive exhibit stands. The lack of daylight makes it essential to have sufficient lighting that is adapted to the requirements of the exhibition events. Zumtobel succeeded in accomplishing this with high-quality luminaires such as TECTON continuous row lighting system and PANOS INFINITY downlights, as well as the comprehensive mix of general, emergency and security lighting. The new hall is unique as Switzerland’s only exhibition hall to meet the Minergie standard.

The characteristic distinction between the women’s and men’s departments at Bershka by using two different colour hues was achieved through the use of IYON, without compromising the typical light atmosphere. The women’s and men’s departments were therefore equipped with luminaires featuring white and black casings, respectively. The fitting rooms, on the other hand, share the same design with the high-efficiency downlightseries PANOS INFINITY. The lighting concept convinced both the building owner and the customers. Meanwhile Bershka has opened two more flagship stores with a complete LED lighting solution from Zumtobel in Frankfurt/Main and London.

With this 22,000 m² shopping centre, which is named “Žilina’s new heart”, the architect has managed to create a fascinating mix of traditional and contemporary architecture. The shopping centre is essentially composed of a circular structure with adjoining rectangular building parts.
In close collaboration with the architect, state-of-the-art luminaires and lighting control systems have been installed to provide maximum convenience and a feel-good atmosphere in passageways, lounge areas and restaurants. In the individual areas, light has been used for varying purposes: providing a brilliant interplay of colours, soft ambient lighting or visual guidance. For the core of the façade, an unusual special LED solution was developed, which reveals itself only when darkness falls. Then, some 2000 LED spots create a magically luminous shell around the entrance. Via DMX control, each compact LED spotlight can be controlled separately.
The interior lighting system features energy-efficient luminaires with daylight-based control and high lighting quality. Uniform ambient lighting in the large hall is provided by downlights. Light lines guide customers through the passageways. For the general illumination of corridors and passageways, the Cielos modular lighting system has been installed: clusters of 2 x 2 luminaires in intermediate light colour create a superior feel-good ambience as well as a seemingly airy ceiling.
In addition to PANOS INFINITY LED downlights, which cannot fail to impress on account of their excellent lighting quality and colour rendering, the Supersystem LED lighting system has been installed. By integrating them into the LUXMATE Professional lighting management system, individual luminaires or luminaires arranged in various groups can be switched on/off or dimmed as required to optimise the quantity of light and thus energy consumption. Even the state-of-the art LED emergency lighting system is controlled and monitored by the intelligent system.

With its new shop concept, SPAR has set an example: almost at the same time, the first climate-protection supermarkets were opened in Austria. For these supermarkets, Zumtobel developed a uniform lighting concept based on LED luminaires only. In combination with other innovative structural measures, the branches save 50% of energy and up to 80 t of CO2.
It was the first time that the TECTON continuous-row lighting system used for general lighting had been fitted with LEDs, resulting in numerous benefits for the client: good thermal management inside the luminaire ensures a long service life of the light-emitting diodes, thus dramatically reducing maintenance efforts and related costs. In addition, the LEDs’ IR- and UV-free radiation is gentle on groceries. TECTON LED’s visual appearance, a consistent narrow light line of extremely high lighting quality, uninterrupted by dark zones at the luminaire ends, is also quite impressive.
In order to highlight shelves and products, LED spotlights were installed in the multi-functional trunking unit. The result is a consistent appearance of the lighting solution in the retail area, while swivelling spotlights enable staff members to flexibly illuminate product displays subject to seasonal changes.
The cash point areas are brightened up by square CAREENA LED luminaires. Arranged consistently above the individual aisles, they facilitate orientation. Even for side rooms and emergency lighting, LED luminaires were chosen, and with good reason: the Panos Infinity LED downlight, for example, is over 70% more efficient than downlights fitted with conventional compact fluorescent lamps. As to the Resclite LED emergency luminaire, the client benefits from its low installed load.

With its store in Frankenthal, Douglas, Europe’s leading beauty store chain, has set standards in terms of resource saving. Following thorough analysis of its power consumption, Douglas has chosen a highly innovative and future-oriented approach to set up an energy management system for the new 300 square metre store. For the first time, the entire lighting system has been implemented using LEDs only. Compared with the reference store in Speyer fitted with conventional lighting technology, it has been possible to save 50% of energy costs by the new lighting solution alone.
Furthermore, saving resources also means using luminaires with longer service lives, so that complicated and costly replacement and storage of lamps become redundant. With their average service life of 50,000 hours, Zumtobel's LED luminaires are the perfect solution. Nearly free from UV and IR radiation, the light emitted by the LED also guarantees gentle illumination of delicate goods on display.
Another benefit of LED luminaires is the option of creating dynamic lighting scenarios. Using the LUXMATE Emotion lighting control system, brightness levels can be adjusted depending on daylight and room situation. Preprogrammed lighting scenes follow a meaningful concept. The levels of lighting intensity can be changed individually at any time, allowing salespersons to personally adjust dynamic colour sequences.
For general lighting, square CAREENA LEDs were arranged in clusters of six luminaires each. Similar to a skylight, these luminaires brighten up the room, attracting customers' eyes into the depth of the room. The special feature of the CAREENA luminaire is its accurate mix of yellow and red high-performance LEDs, producing a pleasant colour temperature of 3500 K that remains stable throughout the entire service life, achieving optimum colour rendering values. Accent lighting and shelf lighting were implemented using gimbal-mounted semi-recessed LED downlights, the luminous flux of which exceeds a 35 W high-pressure discharge lamp and meets Douglas' high demands on colour rendering quality.

The “Body Shop” chain of cosmetics stores makes a point of keeping to environmentally compatible and sustainable methods in manufacturing their product lines. In doing so, the international brand relies on naturalness, not only with respect to cosmetics. Eco-friendly aspects are also taken into account when it comes to shop design and illumination. In Switzerland, the first shop concepts featuring LED-only illumination have now been implemented. The benefits: owing to their compact design, LED luminaires enable unobtrusive installation, especially in smaller shops, while CO2 consumption and costs are reduced thanks to energy-efficient, low-maintenance light sources. All this is combined with gentle high-quality lighting – without any harmful UV radiation and without high levels of thermal output.
Even shops with a rather small retail space of 50 m² convey a pleasant atmosphere, which is particularly obvious in Emmen. This ambience is created by the LED lighting system including PANOS INFINITY LED downlights and DISCUS LED spotlights. Recessed versions of both luminaire ranges have been installed unobtrusively in the grid ceiling. The uncluttered interior design is enhanced by the uniform arrangement of the luminaires. In addition, a large shop window allows passers-by to have a look at the products on display from outside. Thus, the harmonious feel-good atmosphere prevailing indoors is extended towards the street, inviting window-shoppers to enter the store.
Thanks to the LED downlights’ superior lighting quality and very good colour rendering, the retail space is provided with pleasant ambient lighting. Nevertheless, the LED spotlights can be rotated through 360° and pivoted through +/- 90° to provide the shelves at the side walls with exactly the right accent lighting, skilfully putting the focus on the products. Both LED product ranges feature a modern stylistic idiom, very good lighting quality and high energy efficiency. Thanks to luminaire efficiency of up to 77 lumens per watt, which has no equal on the market, PANOS INFINITY in particular shows that high-quality LED technology has by now outcompeted traditional compact fluorescent lamps in terms of efficiency and lighting quality. This makes the LED downlight more than 70% more efficient than conventional compact fluorescent lamps.

Levi’s Green Store situated at the heart of Paris showcases a compact brand world that wholly incorporates the criteria of sustainability into the brand image. Recycling materials and reducing the consumption of energy required for operation are aspects that have been fully integrated into the design concept of the LEED-certified store.
Consisting of steel sections and plain wooden boards, the robust shelves obviously do not resist their patina. Some of the wall elements and free-standing partitions were taken from previous Levi’s stores and recycled at the Green Store. In line with this vintage look, the naked walls in the retail space are bare of any plaster or paint. In terms of ceiling design, the team of designers opted for a reduction of materials and opted against environmentally questionable varnishes or optical covers. Yet, all those technical cables and suspension cords that are visible do not at all interfere with the overall design concept, but rather complement it.
At the Green Store, special importance is attached to reducing power consumption. The store’s lighting system has been developed with a clear focus on LED technology. LEDs allow flexible adjustment to changing seasonal requirements, set new standards thanks to reduced power consumption, and boast a considerably longer service life than conventional light sources. The LED spots installed in the shop window add bright highlights to the jeans models on display. A daylight sensor dims the lighting points depending on incident sunlight and weather conditions. In addition to daylight, the retail space's ambient lighting is achieved by means of four square LED light fields suspended from the ceiling. Moreover, special accents are created by spotlights flexibly mounted on a continuous track fixed on the ceiling. The spotlights can easily be rotated and pivoted to realign them to a new collection as required.
In order to meet the U.S. Green Building Council's high environmental standards, it was necessary to ensure environmental compatibility also with regard to other aspects of everyday life, apart from technological and aesthetic solutions – whether it is using recycled paper in the office, purchasing electricity from a green supplier, or setting up a recycling box for used jeans in the store.

Serbia's most recently opened and biggest shopping centre, the Ušće in Belgrade, combines 140 shops, a number of cafés and restaurants, a multiplex cinema, ninepins alleys and gambling halls and, last but not least, a supermarket with a floor space of 4000 m² to form an integral whole.
The Ušće architecture is characterised by striking contrasts. The dominant façade in signal red attracts customers like a magnet, while the clear, calm and bright interior invites them to stay. “Our task was to create a setting to incorporate many different stores. Therefore we used lots of white – so that all attention remains focussed on the products offered in the retail and food areas”, architect Gerardo Sannella describes the design concept.
The fascinating contrast between inside and outside is continued in the lighting design resulting from close collaboration between lighting designers and electricians. While the façade of the shopping center is brightly illuminated by high-intensity light sources, calming accent lighting is provided by the luminaires inside. The galleries are spanned by wide atriums incorporating three “naves” and four floors. In the evening, daylight is replaced by a combination of XENO spotlights and MIROS projectors/mirrors providing soft light flowing downwards. Suspended ceilings, recesses and protrusions create spaces to accommodate a continuous-row system where relaxing zones alternate with stimulating areas.
Above the main entrance and in the central areas, warm and bright light is provided by luminous ceilings. In addition, downlights provide pinpoint accent lighting to guide visitors along the shopping streets. Now and then, narrow light lines reminiscent of illuminated bar codes have been added. Most luminaires can be dimmed, which is perceived by visitors as more attractive than illuminance levels that never change. The entire installation is controlled via the LUXMATE Professional lighting management system.
At the Ušće shopping centre, architecture and lighting have been matched perfectly to supplement each other in an ideal manner. It is not the individual luminaires that are put centre stage, but the overall impression.

All their lives, Armand and Martine Hadida have strived for perfection. The visionary couple has now opened their sixth showroom. Claiming to be more than a simple retail store, the most recent offspring perfectly fits into the chain of existing stores. Whether selected designer fashion or the highly coveted Microsoft Surface Table, there is room for everything at L’Eclaireur – except for boredom.
“It is not a store, it is an experience”, is how Arne Quinze describes the most recent branch of L’Eclaireur. On a floor space of 450 m², collections by renowned designers from all over the world are presented. At L’Eclaireur, it is the combination of state-of-the-art high-end technology and recycled materials that creates a fascinating field of tension. Two tons of untreated wooden planks, ancient printing plates and card-boards sprayed with gloss paint provide a marked contrast to the 147 animated video screens showing the eyes of shop designer Arne Quinze's wife, Barbara Becker.
The interplay of light and shadow has been choreographed by a skilful master. The person responsible for this is lighting designer Aysil Sari, who, in collaboration with Zumtobel, developed the SUPERSYSTEM lighting system, which allows focussed illumination also from great heights. The track-mounted 2.5 W LED spots boast UV- and IR-free lighting without producing any heat – qualities which are especially important for the presentation of clothes. The elevated areas and the changing rooms are illuminated in a multi-facetted way by a further developed version of SUPERSYSTEM, a square 4-spot module. “Someone who chooses an extraordinary shop concept like that is not looking for a ready-made lighting solution, but a futuristic solution. In collaboration with Zumtobel it was possible to develop and implement such a solution”, the lighting designer explains.
