I think I've discovered the worlds cheapest LED shop lights $15 each in 4-pack. These are great plastic, super light-weight but like most shop lights, they lack the surface mount ability. With vent holes on the side, minimal air gap should be required with these so I created a slip-on bracket that will fit to either the inside or the outside allowing you to mount it flat to a surface with a single screw (or molly/toggle depending on the substrate you're mounting to). this was designed to mount these directly to a glue-lam beam in my office.
