I have no experiance with actual assembly of lighting systems, but have noticed while at Home Depot, picking up cheap fixtures, that they sell all of the individual parts to assemble a fixture. I'm curious about just how hard it would be to get a couple of the end pieces (where the bulb rests) the ballast, and just size things as appropriate in a diy hood?? when I have been assembling the fixtures I have, they sure dont look like there is much to them, and sure would seem to be a cheaper method of building a hood then even buying the twin strip shop lights.. just looking for feedback.
