This LED motion sensor light has 3 aimable light heads and emits 3000 lumens of natural or warm white illumination. A sliding switch allows you to choose between 3 operating modes. Auto mode uses the light's aimable PIR (passive-infrared) sensor to activate all light heads if motion is detected. In this mode, you can customize lux (daylight level when lights will activate), on-time, and detection range (up to 70') with built-in dials. Dusk-to-dawn mode powers the lights on at dusk and off at dawn. On-time mode allows the lights to remain on constantly. The weatherproof LED safety light is constructed of a durable aluminum alloy housing (white or brown) and polycarbonate lenses. This motion sensor light consumes just 30 watts of power—significantly less than the 150 watts that would be required from an incandescent fixture—while lasting 42 times longer. It operates on 100-277 VAC and includes a bracket, foam mounting gasket, and installation hardware for junction box mounting.
