Espen's VEMB20W LED emergency driver operates Espen Flex and Flex DE Type B LED T5 and T8 lamps. During a power outage, the VEMB20W provides up to 20W of power to the lamp, allowing the same fixture to be used in both normal and emergency mode. At 20W, this emergency driver illuminates most TLEDs at full brightness.
