DALI

DALI stands for Digital Addressable Lighting Interface and is a digital control option for luminaires.
More precisely, it is a manufacturer-independent interface standard for dimmable electronic ballasts. With DALI it is possible to control several luminaires or electronic control gears with only a few wires.
In addition, DALI can be integrated into higher-level building system technologies such as KNX, EIB (European Installation Bus) or LON (Local Operating Network).
