The leading Human Centric Lighting technology “PI-LED” was integrated on a module width of just 12 mm in order to enable dynamic, season-independent daylight curves from morning red via midday blue to evening sun incl. individual lighting scenarios. With 132 lm/W, the PI-LED Edge Light System is the only solution in the world to make Human Centric Lighting possible, even in extremely low installation heights and for super-flat luminaires.
