How do the strip lights compare to the bulbs? I'm thinking it might be easier to have 5 of the 18" wide ones attached to the underside of a 22" piece of board with 3 wooden sides keeping it upright. A panel at the back, two at the edges and nothing on the front or underneath. That'll sit ontop of a work surface when I'm using it then and can get taken in and out of the darkroom.
