FEATURES & SPECIFICATIONS
INTENDED USE — The LEM08 emergency LED driver enables the lighting xture to deliver a minimum
of 90 minutes illumination during a loss of normal AC power. It is cUL Listed for factory or eld installation
with indoor, damp location luminaires utilizing 20-50VDC output voltage.
CONSTRUCTION
UL rated, painted steel enclosure (white)
Flexible metallic conduit
PERFORMANCE — When normal AC power fails, the LEM08 immediately drives the LED load at reduced
light output for a minimum of 90 minutes. When AC power is present, the emergency LED driver ensures
the sealed, maintenance-free, high-temperature nickel-cadmium batteries are fully charged within 24
hours after a discharge and remains fully charged until the next loss of AC power. The included test switch/
pilot light provides visual and manual means of monitoring the system operation.
