Industrial LED lights are the heavy-duty, super-bright alternative to traditional tube light fixtures. Perfect for commercial lighting, warehouse lighting, parking garage lighting, tunnel lighting, supermarket lighting and more, this 4' low-bay LED light has 288 enhanced 2835 Epistar SMD LEDs with an output of 4,500 lumens. Natural white LEDs have a 4700K color temperature and emit a wide 180° beam angle. This powerful, energy-efficient LED light fixture uses just 50 watts of power—significantly less than the 128 watts that would be consumed by a metal-halide (MH) fixture. And with a life expectancy of 50,000 hours—5 times as long as fluorescent or MH fixtures—the LED light reduces costly repairs, disposal fees and the need for replacements. A vapor-proof, weatherproof aluminum housing and frosted polycarbonate lens are dust tight as well as water and impact resistant for use in harsh environments. Mount on a wall with included hardware or suspend from ceilings up to 15' high with a suspension kit – sold separately. Also available in a 2' long 30W version.
