To complement the lavish restoration that was befitting for such a monument, the symbol of the capital was also given a completely new, state-of-the-art lighting system. Amongst other fittings, the lighting designers at Kardorff Ingenieure, design office in Berlin also chose 70 Tesis lens wallwashers for floor installation, fitted with 35W metal halide lamps. These were assigned to the individual columns. Two Parscoop floodlights for 70W metal halide lamps are mounted in each ceiling of the five main passages and illuminate the passage wall surfaces.

ERCO lighting tools thus play a decisive part in a lighting concept whose quality does justice to the great significance of this building.
