LED driver and emergency lighting unit combined

power LED BASIC 75 W linear features an LED driver from the excite series and an emergency lighting unit combined in one housing. 

This means that it takes up less space in the luminaire and saves on wiring. The integrated emergency light converter covers an output power range from 6 to 75 W and spans 1 to 3 hours of operation. The broad power range enables a single device type to be used for a wide variety of luminaire types. The device is designed for linear luminaires and low-profile luminaires with single-battery emergency lighting systems.
