During the design stage, highest priority was therefore given to a flexible lighting solution to enhance the building's architecture and ensure high lighting quality. In addition, the lighting scenario creates a pleasant atmosphere for visitors and staff. The Austrian lighting expert Zumtobel was called in because both the client and the architect needed a top-class partner with international experience and premium advisory skills. Zumtobel developed a custom-made lighting concept involving a number of special solutions for the various functional areas in the Werkraum House. For the part of the building that is open to the public, where various Werkraum members exhibit their work, Zumtobel used 100% cutting-edge LED technology.
The LED option cannot fail to impress thanks to its easy integrability into a lighting management system, so that the lighting can be flexibly controlled whenever events or exhibitions are held. “Lighting is especially important when it comes to presenting the achievements of our craftspeople in the right light in a targeted manner. On the other hand, it is precisely the light, in combination with acoustics, that sets the stage for a room's atmospheric qualities. Here at the Werkraum House you can see a sophisticated combination of artificial lighting and daylight,” says Managing Director Renate Breuss. In order to ensure perfect room acoustics, the open hall of the building where events are held was fitted with a thickly cushioned coffered ceiling made from timber. Zumtobel used a specially designed suspension system to install some 160 LED spotlights of the Panos Infinity range in this area. These downlights provide uniform ambient lighting as well as especially good lighting quality and are also highly efficient. Additional accent lighting and excellent colour rendering are ensured by nearly 90 swivelling Vivo LED spotlights, also fitted with a special pendant suspension system, which are used mainly for highlighting individual exhibits. Hence, Vivo provides accent lighting, creates contrasts and puts the focus on the exhibits, ensuring a fascinating art experience for the visitor.
In order to allow simple connection of the luminaires to the power supply and lighting control system as well as integration of an emergency lighting system, the Tecton continuous-row lighting system is used. This allows quick adjustment of the lighting solution to changing requirements thanks to no-tool installation. Moreover, Zumtobel has proved its flexibility in implementing individual requirements by providing a custom solution for the staircase and sanitary areas. Special downlights were flush-mounted in the concrete ceiling. They provide ideal lighting conditions to facilitate orientation and guidance and at the same time enhance the room's architecture. For emergencies, Zumtobel has installed Puresign and Resclite LED luminaires in the building. On the basement level, perfect orientation is ensured by suspended Tecton luminaires fitted with fluorescent lamps and rugged Scuba luminaires providing uniform lighting.

Zumtobel. The Light.
The slimline design with a height of only 28 mm is made possible because the light emitting diodes have been integrated into the frame of the pendant luminaire. In order to obtain a well-balanced indirect/direct light ratio, LED light is emitted downwards thanks to litePrint light guide technology. The precisely calculated dot matrix of the litePrint light guide ensures uniform illumination of the complete light emitting panel. At the same time, an exactly defined light component is directed upwards, in specific regions, via openings in the luminaire housing, so that no extra LED modules are required for the indirect component.
Plenty of creative scope for modern office environments that are often modified is provided by the free-standing luminaire. Available with three different luminous flux levels (7,800, 11,000 und 14,800 lm) as well as warm and intermediate colour temperatures, the Light Fields evolution free-standing luminaire offers a variety of application options. The swarmControl technology used here is characterised by two functions that ensure a new dimension of individual lighting quality at workstations: the corridor function and the presence-based function. The fiormer primarily provides for safety and orientation, as the luminaires are dimmed up one by one by means of a built-in presence detector, thus indicating the way to the workstation. The presence-based function, on the other hand, ensures ideal lighting conditions with a mean illuminance level of up to 500 lx at the workstation, while users may adjust the quantity of light to their personal needs at any time using a control panel in the luminaire base. Neighbouring luminaires communicate via swarmControl, providing a cloud of light that creates a pleasant working atmosphere. The sensControl III function increases the free-standing luminaire's efficiency even more. The presence detector automatically switches the luminaire on and switches it off again when the workstation is left unattended. A brightness sensor monitors the illuminance level across the desktop and dims the luminaire depending on the quantity of daylight or artificial light available. Thus, up to 70 percent of energy can be saved, compared to conventional switchable free-standing luminaires.
Zumtobel. The light.
Perfect lighting quality for a variety of working situations is provided by the patented micro-pyramidal optic (MPO+). The optic's diffuser layer resolves the LED points perfectly, while the high-precision formed micro-pyramids ensure superior lighting quality. The luminaire elements feature innovative technologies providing the best light for workstations. The 3Dprotect reflector protects the LED modules, effectively preventing damage from electrostatic discharge during installation. In order to obtain a well-balanced relation between indirect and direct light, LED light is emitted up-wards and downwards thanks to litePrint light guide technology. Two colour temperatures are available for the luminaire (3,000 K and 4,000 K). With a luminaire efficiency factor of up to 105 lm/W, the LED luminaire also makes a significant contribution towards sustainable added value.
ARCOS xpert LED spotlight
Thanks to its perfect lighting quality and innovative reflector technology, the Arcos xpert LED spot-light cannot fail to impress in museums and art galleries.

Thanks to a sophisticated optical solution and constant colour temperature of light emitting diodes, the standard 620 mm version and the short 320 mm version of this dimmable linear wallwasher ensure uniform illumination. Zumtobel relies on top quality in terms of materials as well: the housing is made of extruded aluminium sec-tion, with die-cast aluminium front sides.
VIVO LED spotlight system
For accent lighting in shops and small retail spaces, Zumtobel has added the small Vivo XS spot-light to the Vivo spotlight system and now also offers an LED version of the Vivo M spotlight. This rounds out Zumtobel's LED spotlight range for retail lighting, which now includes suitable lighting solutions for small boutiques with low ceiling heights as well as for display windows and for shops with high ceilings, so that products can be set centre stage in a targeted manner.
The small size of the Vivo XS spotlight is made possible by a combination of compact LED mod-ules and innovative cooling. When looking for a suitable design language, the EOOS designers let themselves be inspired by the shape of a turbine. Thus, the Vivo spotlight makes use of the airflow that is essential for cooling.
Vivo M, one of the most successful products in the Vivo spotlight range, is now also available as an LED version. Thanks to its excellent colour rendering index of more than Ra 90, glare-free light and especially uniform light distribution, the compact and versatile spotlight cannot fail to impress when used for shops or display windows.
IR and UV-free technology makes it possible to illuminate sensitive products, such as groceries for example, very gently. Thus, fruit and vegetables remain luscious, meat stays fresh and textiles retain their colours.
Moisture-proof LED luminaires
Special conditions apply to car parks when it comes to lighting. In addition to the protection rating required (IP 65), the requirements in terms of material and quality are high as well. In addition to the existing portfolio of Chiaro II and Scuba LED moisture-proof luminaires, Zumtobel has now added models with higher luminous flux levels.
The Chiaro II 840 moisture-proof luminaire now optionally delivers 5,900 lm or 6,400 lm with a watt-age of 54 W and is available in either an intermediate or cool colour temperature. Chiaro II achieves significant potential energy savings thanks to its luminaire efficiency factor of 109 lm/W at a colour temperature of 4,000 K or 118 lm/W at 6,500 K.
With an installed load of 54 W, Scuba LED now offers a choice of luminous flux levels of up to 5800 lm (Scuba LED 840) or up to 6300 lm (Scuba LED 765). Two colour temperatures are avail-able depending on specific needs: 4,000 K or 6,500 K. In case of continuous operation, moisture-proof luminaires with a luminaire efficiency factor of up to 108 lm/W (Scuba LED 840) or up to 117 lm/W (Scuba LED 765) have proved to be efficient lighting solutions.

“The new exhibition layout of the Royal Cabinet of Mathematical and Physical Instruments sets the masterpieces of the collection centre stage. Thus, visitors can enjoy the beauty and technical brilliance of the devices made for the Saxon Court up close and down to the finest detail. Media stations and presentations of historic experiments using replicas illustrate the functions of the instruments that were used for active research on site, at the Dresden Zwinger” – this is how Hartwig Fischer, General Director of the Dresden State Art Collections, explains the new concept. The lighting solution plays an important role against this background: it accompanies visitors along the galleries and pavilions, facilitating orientation and ensuring that they can experience the instruments authentically, while at the same time allowing for targeted and gentle presentation.
LED opens up new opportunities
One of the most important decisions in the context of the new concept was the changeover to an LED-only lighting solution. The minimalist Supersystem LED spots blend unobtrusively into the interior, enhancing the Baroque architecture to optimum effect. It is, however, not only their reduced dimensions and low energy consumption, but above all the LED luminaires' excellent lighting quality that is so impressive: since the new generation of LED luminaires emits significantly less heat and the light they generate is nearly completely free from IR and UV radiation, potential damage is reduced to a minimum. Outstanding colour rendering of more than Ra 90 allows visitors to experience the exhibits in their natural appearance, which could not differ more in terms of materials and colours, for since silver is presented to optimum effect in cool white light colours, warm white is ideal for shades of gold and bronze.
Some 400 exhibits are set centre stage authentically yet gently by approximately 1100 LED spots. Thanks to their performance potential, accent lighting is possible even across longer distances. Here, the modular lighting system is able to proof its outstanding versatility. Depending on the lighting task, various Supersystem models have been installed in the entire exhibition area as well as in public spaces: recessed in the ceiling, surface-mounted or as pendant luminaires. Moreover, the individual spots can be swivelled in and out and rotated in all directions to provide selective accent lighting.
Another characteristic feature of the new lighting solution is the interplay of daylight and artificial lighting. In the bright galleries, which were originally not intended as museums and meet conservational requirements to a very limited extent only, a great deal of sensitivity was necessary to integrate air-conditioning and light-shielding devices in order to protect the precious and sensitive exhibits. Thanks to a built-in DALI unit, Supersystem is compatible to a variety of lighting management systems, and the spots can be subdivided into useful control groups, adjusted to the prevailing lighting situation and set to ideal luminous intensity levels to suit the respective exhibition situation. “The combination of artificial lighting and daylight has been especially adjusted to the requirements of the interior design. State-of-the-art LED technology allows even the presentation of sensitive exhibits in a contemporary fashion, while the original flair of the premises is preserved,” explain Raoul Hesse and Carla Wilkins, the design team of Lightvision, the lighting design studio in charge, who are very pleased with the results.
Zumtobel. The Light.
The newly opened “Museum Ton Schulten” in Ootmarsum is far more than an artistic biography of Ton Schulten, one of the most successful and renowned contemporary Dutch painters. In several rooms, he not only displays his own oeuvre, but also selected works of art by a number of international artists. He placed particular emphasis on an authentic, yet gentle lighting concept. In Zumtobel he found a partner who was able to perfectly implement his demands in terms of colour rendering quality, flexibility and conservational requirements.
Excellent colour rendering
Most of Ton Schulten's paintings show landscapes where nature shines in all her colourful splendour. Visitors are supposed to get the impression of standing right in the middle of such a landscape, experiencing it in natural sunlight. Against this background, the lighting solution faces particular challenges, for while bold blue or green shades are presented to optimum effect in cool white light, warm white is ideal for red and yellow. Hence, colour rendering and colour brilliance were very important aspects in Ton Schulten's decision for the right lighting solution. “I am highly satisfied with the result, because the paintings are presented in a very natural light so that they can unfold their full effect,” says a pleased Ton Schulten.
The solution was provided by a customised version of the Arcos LED spotlight system boasting a colour rendering index of up to Ra > 95 at 2700 K. In order to set the perfect lighting stage for presenting the artworks, a total of 230 spotlights were installed on Supersystem tracks. The dimming level can be adjusted directly on the spotlight, which allows individual adjustment to any exhibit. In addition, a variety of beam angles and an oval outline lens ensure sufficient flexibility to solve the most diverse lighting tasks.
Gentle and efficient illumination
However, the LED lighting solution was able to outcompete conventional halogen lighting not only due to excellent colour rendering, but also thanks to its compliance with conservational requirements. “As the new generation of LED luminaires emits significantly less heat towards the precious exhibits and the light they generate is nearly completely free from IR and UV radiation, we can ensure gentle illumination for sensitive objects as well,” says Barry Harmes from Zumtobel who was involved in the project from the beginning.
This was further corroborated by a study conducted by Zumtobel in collaboration with the Lighting Engineering Department of Darmstadt University of Technology. As part of this study, the quality of various light sources was tested on a real object of art, Picasso's “Harlequin” drawing, using predefined evaluation parameters. Basically, potential damage caused by the LED spotlight is significantly lower at comparable colour temperatures. At the same time, energy efficiency is increased by the LED spotlight, as the input of electrical energy is around 50 percent less than with a halogen spotlight. An additional benefit is the LED's long service life, combined with reduced maintenance effort.
