If your not sure what to look for you are probably better off buying a retro kit on line. You are going to have to buy the appropriate bulb some where else even if they have the appropriate ballast, socket, and you are able to make a reflector. You can find retro kits that are fairly cheap and are pretty much ready to go. It is probably less of a fire hazard as well. I'm not trying to be negative, but give a different perspective on the idea.
