In the less sensitive manufacturing area, the flexible light strip system SRT is installed. It can be quickly installed thanks to plug-in device holders and individually adapted to the track system. (Photo: hansedknoedler.de for Regiolux)

The office workplaces and meeting rooms are also optimally lit: The insert lights lowea blend seamlessly into the acoustic ceilings and provide glare-free, uniform lighting. (Photo: hansedknoedler.de for Regiolux)

At SpaceTech in Immenstaad, solar modules for satellites and laser optical instruments for earth observation are produced – components that determine the energy supply or the success of entire missions in space. Accordingly, the requirements for the two company buildings, which the company erected due to strong growth, were very high. Architect, planner, and client sought from the beginning a lighting partner who delivers object-specific solutions of the highest quality and can respond flexibly to planning changes during the construction phase. The choice was deliberately made for Regiolux, as SpaceTech Managing Director Frank Gilles emphasizes: "We specifically chose Regiolux as a German manufacturer to always ensure high-quality LED lighting. Both in the office and in the cleanroom where we manufacture our space components."

Consistent concept for different areas of application

Manfred Schwägler Elektrosysteme from Owingen planned and implemented the lighting for both new buildings, working closely with Regiolux. Together, they developed a concept that covers cleanroom zones, manufacturing, administration, and ancillary areas equally. Particularly advantageous for on-site installation were the plug-in device modules, the through-wired SRT light strip system, the easy-to-mount details on all luminaires, and the DALI-compatible components. They enabled quick installation and a smooth process.

Already in the first construction phase in 2021, it became clear how flexibly the lighting manufacturer from Königsberg responds to object-specific requirements: demanding were a wide-beam, efficient hall lighting, cleanroom-compatible luminaires for sensitive production zones, and reliable DALI integration. In the offices above, a harmoniously coordinated ceiling lighting was to be used, which is also ideal for screen workstations. The project manager of the electrical specialist company relied on his good experiences with Regiolux and took a holistic approach, relying entirely on Regiolux's expertise for this demanding project. Around 90% of the Regiolux luminaires were already installed in the first hall and convinced in terms of quality and handling – a result that immediately led to a follow-up order for the second hall. By the overall completion of the project in 2025, a consistently coherent, practical, and economical lighting concept was created.

Cleanroom quality and homogeneous manufacturing lighting

In the cleanrooms, the aduna luminaire with IP65 protection class for high dust and water jet protection and multilayer light technology is used. This optics ensures a particularly uniform, glare-free illumination, which is necessary for visually demanding work on highly sensitive components. The closed, cleanroom-compatible design guarantees permanent tightness, particle protection, and easy cleaning – essential prerequisites for controlled production processes.

In the other manufacturing areas, the quick-mount light strip system SRT from Regiolux is installed. The plug-in device holders with factory-integrated wiring enabled quick and safe installation. The flexible segmentation of the light strips is particularly advantageous: different work areas can be illuminated individually without interrupting the uniform lighting concept. 10,000-lumen device holders provide energy-efficient basic lighting that can be controlled as needed via DALI.

Optimized lighting concept for administration and technical areas

When the architects quickly chose visible acoustic ceilings for some areas, Regiolux responded promptly with suitable luminaires from the lowea product family. Where lowea surface-mounted luminaires could not be used, lowea inset luminaires integrated flush into the acoustic ceilings, providing glare-free, uniform light at technical workstations and in offices. Installation-optimized details such as an integrated suspension safety device for surface-mounted luminaires and the additional push-feder locking in all versions significantly facilitate installation.

Downlights from the relo series with diameters of 140 mm and 190 mm evenly illuminate corridors, stairwells, and auxiliary rooms, while their compact design and flexible mounting options consider different ceiling heights. The variety of options across all luminaire types from Regiolux allowed for a consistent and aesthetic lighting concept in both buildings despite changes in ceiling geometry.

Sustainability and efficiency in focus

SpaceTech places great importance on quality as well as sustainable and economical technologies. The high luminous efficacy and longevity of the Regiolux luminaires significantly reduce energy and maintenance costs. In combination with DALI-based control, this ensures efficient and ecological operation, in line with the company's philosophy.
