The lighting design firm Lichtvision was commissioned to develop a concept to illuminate the facades of the Humboldt Forum. The result was an intentional lighting of the facades in terms of intensities of illumination and their distribution.
The lighting design bathes the building in a uniform light. It accentuates the mighty presence of the Royal Palace in the heart of Berlin. The flat evenness of the light without much shadowing places priority on the building's three-dimensionality over its details so that it appears imposing and grand, especially from a distance. The height of the light points is necessary to avoid casting hard shadows and to create a uniform lighting.
The designers' lighting specifications were based on standard luminaires. Their design then needed to be integrated into the light columns that also illuminated the exterior areas. KARDORFF was commissioned with achieving these two tasks by using one type of light column.
First, the positions for the light columns were chosen by Kardorff Ingenieure to ensure that the entrances and views of the palace remained unobstructed. The desired light distribution at the defined positions had to be recalculated for the luminaires that can be used in Selux's LIF light column. The LIF light column was custom designed by Kardorff Ingenieure and has highly complex facade modules which can precisely aim individual LED using many separately adjustable deflective mirrors.
This made it possible to achieve the same lighting effect even with another product and at other positions than Lichtvision had originally designed.
As a result, the illumination of the square and the facade have been integrated into one luminaire.

To illuminate this imposing building, a patented spotlight system with projection glasses was used for the first time in Germany. Using this state-of-the-art technology, the facade is lit horizontally, free of glare, and very energy-efficiently. The power consumption is 2 kW, less than 1 Watt per square meter of facade.
