TS was contracted via the LTS sister company Fagerhult NL with the aim of creating both a sustainable and an aesthetically attractive lighting solution. The client’s requirements were specific and a customised solution had to be designed. In 2023, De Langen & Van den Berg, a building contractor and developer from Bergambacht, south of Rotterdam, brought this ground-breaking project to life: a new, climate- neutral office building. Using solar panels, heat pumps and a high-quality thermal building envelope, the building achieved the ENG standard which means zero annual energy consumption. The entire electrical installation was provided by Rehorst Elektrotechniek. Fagerhult NL supplied both the LTS luminaires and the related equipment.
After consultation between Fagerhult NL, Rehorst Elektrotechniek and the client, the partners suggested a lighting technology and concept that met all requirements. CLO (constant light output), used for a majority of luminaires, is particularly worth mentioning in this context as it extends the service life of LED components considerably.

The quality luminaires have one of the highest light output ratios that the market currently has to offer. All components of the LTS Lichtkanal – the housing, the control unit and lighting technology –complement each other and have
The core component of the solution developed by LTS for the office building is the state-of-the- art LTS Lichtkanal 060. Aside from energy-related aspects, the decision was also influenced by the architectural features. The building contractor’s individual requests were met. The Lichtkanal luminaires seamlessly integrate into the corridor ceiling which is furnished with wooden lath profiles. The light lines placed precisely along the edge of the ceiling and wall create the effect of walls being flooded with light. They harmoniously blend into the architectural contours of the building. The linear light line provides both for efficient lighting and creates an impression of visual continuity along the entire corridor. Having the right light in hallways or corridors is paramount when it comes to welcoming guests and improving the wellbeing of employees. The LTS Lichtkanal elegantly follows the corridor contour, guides visitors and employees clearly to the desired rooms and enhances the quality of the time spent in the transitional areas of the building.
Integrating the LTS Lichtkanal fulfils the need for sustainable and advanced lighting solutions. It also offers other benefits, such as:
• Individual adaptation and made-to- measure production for any architectural requirement • Reduction of lighting energy costs by up to 75% • Efficiency increase thanks to optimum light quality and light distribution • Compliance with RoHS directive and EU Ecodesign regulation • Sustainable solution thanks to LEDs with a long service life • (50,000 operating hours, almost maintenance-free)
been technically adjusted to reach a premium, state-of-the-art level. LTS has scrutinised, tweaked and tuned Lichtkanal to increase its efficiency. The installed Lichtkanal solution is even more powerful and features the lowest power consumption any Lichtkanal has ever had. Continuous, uninterrupted light is possible thanks to infinite light control films. Less material is used to save resources, which contributes to the environmental benefits. LTS Licht & Leuchten shows that modern lighting solutions can excel from an aesthetical perspective and make a considerable contribution to sustainability and energy efficiency at the same time.
LTS Lichtkanal 060 is the heart of the lighting concept in the office building by De Langen & Van den Berg, because the corridors connect all of the rooms. With an impressive efficiency of 167 lm/W and seven different light distribution solutions, it improves the looks of every building and offers optimum guidance and directional lighting. As Lichtkanal is adjusted to the architecture of the building, it not only emphasises architectural features but also contributes to optimising energy consumption.
The successful integration of LTS luminaires into the energy-efficient building by De Langen & Van den Berg is a prime example of the harmonious combination of sustainability and innovation. The project’s sustainability strategy has been backed consistently by selecting the right state-of-the-art and energy-efficient LTS luminaires. Using the CLO technology and made-to-measure lighting solutions enabled both a reduced energy consumption and a seamless integration into the building’s comprehensive ecological vision. The innovative LTS luminaires make the building more environmentally friendly enhancing its beauty and function at the same time: a well-conceived overall concept. This smooth interplay between sustainability and state-of- the-art technology clearly highlights the shared vision of both companies to create advanced and environmentally friendly solutions for a greener future.
