The VEML25MV-1, LED emergency driver works in conjunction with the LED driver to allow the same LED fixture to be used for both normal and emergency operations. When power fails, VEML25MV-1 switches to emergency mode and keeps the luminaire illuminated at a reduced lumen output for a minimum of 90 minutes. VEML25MV-1 is suitable for use in new LED fixtures or LED retrofit applications. Includes LED charging indicator light, single-pole test switch, battery and installation hardware.
