Cost-effective emergency LED driver

The emergency driver is UL Listed for factory or field installation in the U.S. and Canada. It allows the same LED luminaire to be used for normal and emergency operation. The BSL4L works in conjunction with a Class 2 AC LED driver that has an output current not to exceed 3.0A and provides emergency mode output of up to 520 lumens.* The BSL4L consists of a high-temperature nickel-cadmium battery, proprietary charging technology and electronic circuitry in one case. It can deliver up to 4W to an LED load (15 -54 VDC) for a minimum of 90 minutes. If used in an emergency-only fixture, no AC driver is necessary. The BSL4L is suitable for indoor and damp locations and also for installation in sealed and gasketed fixtures, including fixtures rated for wet locations. For more information about specific LED and AC driver compatibility, please call the factory.
 

*Based on a min efficacy of 130 lumens/watt of load power.
