Hey guys, I'm a total noob to flashlight modding but I want to rebuild an old 3 D Cell Maglite I have. I have already converted in to a TerraLux LED and I want to upgrade the reflector and glass as well. I have seen a ton of different aluminum reflectors and I'm not sure which will fit or work best. I red the reflector shoot out on here but what I guess I'm finding is most are 52 mm x XX mm and I'm not sure what second measurement I need to fit over this LED and throw a good amount of light. I'm not an expert but I do want something that does away with the "hole" in the middle of the stock beam and something aluminum as the plastic ones seem to dry out after a few years. Thanks guys!!!!
