Single swing-arm work lights adjust both horizontally and vertically to focus the light from the LED bulb into the truck trailer or any other desired direction to help improve worker safety. A polycarbonate lamp head helps protect the PAR38 LED bulb from impact damage, focuses the lighting in the desired direction and stays cool to the touch making it ideal for refrigerated and food service applications. The 24" swing arm will withstand most blows from a closing dock door or passing fork lift reducing maintenance and replacement costs.
