The ELM4L from Lithonia Lighting® is an aesthetically pleasing emergency LED light fixture. It provides a minimum of 90 min of illumination when there is a loss of power. Equipped with four high performance LEDs and full range swivel lamp heads it is ideal for a wide range of mounting height applications (from 7.5 to 24 ft), requiring aimable optics. The linear pattern provides wide uniform distributions that deliver broad spacing up to 67 ft and low max to min ratios that far exceed code requirements. The ELM4L optional lithium platform comes standard with universal input voltage (120 to 347 V). The upgraded lithium iron phosphate battery provide extended run times of up to 4 hr or up to 32 W of remote capacity. Also, remote testing and self-diagnostics that meet and exceed code required testing while significantly reducing the time and cost of compliance. Plus, constant light output over the full discharge period.
