A flexible dock light arm allows you to position the arm with ease to direct the light exactly where you need it whether that be the back of a truck or trailer or to illuminate a workbench or specific task. With the FlexPro’s arm design, users can expect an impressive range of motion and a sturdy arm that will remain in place once set in position.LED dock lights make great task lights. The arm allows the light to be pointed at a specific location and the high lumen output provides the right amount of light to illuminate your task. Power switches on the head or arm make it easy to turn your task light on and off while you’re working. The Phoenix DLA 2 or FlexPro are great examples of LED task lights.
