The Dock Loading Light minimize freight damage while expediting loading and unloading operations. Designed to provide uniform visibility inside trailers or around dock areas. This light offers much higher lumens/watt output and a very long lamp life. Its illumination color rendition (yellowish) is not as desirable as an incandescent. The light typically requires several minutes to fully illuminate, and even longer if in a cold environment. Low operating cost and can be used in damp locations. UL listed.
