I replaced a bad double 4' fluorescent hung over my truck with the one hanging over my workbench, then added two single 4' LED fixtures over the work bench (Northern Tool, $19.99 ea on sale). I love them! They are bright, silent, and the light is slightly warm instead of the cold bluish fluorescent light. I put the LEDs over the front edge of the work bench instead of against the wall where the fluorescent was, so each will light the bench and the underhood area of each car. The LEDs are pull string, while the fluorescents are on the light switch, so there are options.
