Along the entire historical fortress wall, the lighting designers have arranged hundreds of linear flood-lights in a special installation trench. The grazing light creates a dramatic impression and emphasizes the highly varied surface of the old walls.

To illuminate the surfaces effectively and economically, the lighting designers arranged a row of Focalflood floodlights for 26W TC-TEL compact fluorescent lamps along the wall of the new building. Floodlights with axially symmetric light distribution provide uniform illumination of objects or surfaces. The light distribution has a point of focal emphasis.
