My four “fluorescent light” fixtures are ready to suspend from the shop ceiling. There is one problem; there is no ceiling in this shop. The shop has four fixed walls and a removable plexiglass cover. I will make the light fixtures look like they hang from the ceiling.
I made a center “ceiling joist” to support “rafters” of 1/4″ polystyrene square tubes. The joist will have notches to support the rafters and keep the spacing. The wires for the lights will run through the hollow rafters.
Most shops have fluorescent lighting suspended from the ceiling. Have you ever tried to find fluorescent lights that didn’t cost and arm and a leg? Either I was looking in the wrong place, or I was presented with another of those opportunities to draw from my Popular Mechanics DNA.
I thought I had seen somewhere that a cool white LED chip attached to the open end of a polystyrene tube would resemble a fluorescent light. Experimenting, it seemed that a light at each end of a 2” piece of 1/8″ tube would give a pretty good effect. Now I needed to configure a box that would hold the tubes and chip lights firmly in place. I used some styrene and ABS extrusions from Plastruct. I used 1/2″ ABS channel for the bottom and .187″ half round styrene rod for the sides.
