To create a lighting situation which enables both good work and an appropriate atmosphere despite a low room height, LIGHT ON uses two complementary systems. The key element is provided by LED strip lighting with an opal coverage which are installed in a ceiling opening. To illuminate the ceiling and the ceiling opening on a simultaneous and even basis, the strips’ protrusion from the recess is unnoticeable. In addition to this, the ceiling sections, which make the room look higher, are illuminated by invisible LED strips. Different colour moods can be chosen freely. The entire lighting system was tested for its light intensity, while the photometric data and colour reproduction values of the LEDs were recorded and measured to precision.
