Industrial low bay LED vapor-proof lights are the heavy-duty, super-bright alternative to traditional tube light or strip light fixtures. They're perfect for commercial lighting, warehouse lighting, parking garage lighting, tunnel lighting, supermarket lighting and more. This 4' low-bay LED light uses just 50 watts of power and emits 6,100 lumens of cool or natural white illumination—equivalent to the output of approximately 2 32-watt fluorescent T8 tubes. And with a life expectancy of 50,000 hours—5 times as long as fluorescent 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.

Important Notes - Please read before purchasing:

great light, easy install

We placed three of these lights in the covered entry at our church. they range from 10-12 ft up. the color temp is great. they say they have a 120 degree range but i'd say it's a bit better than that... seems more like 150 degree. They were easy and quick to install using the clips provided. The instructions were a bit basic, but who reads those anyway, right? Make sure you put the tightening screw into place prior to installing the light.

Nice looking fixture

Been using for a few weeks now. Fixture is well made and looks nice, not "industrial". It sheds a bright, well diffused light that illuminates my shop well without the blinding glare some LES fixtures create. 50w replacing 580w of various types of bulbs - a nice energy savings! I bought the 2' version, as well, for above the workbench but haven't had time to try it yet. I wanted to switch to LED, in part, because the fluor tubes are very dim in the winter when the shop is unheated. I would recommend this to anyone...
