I order my stuff from blose hollow trading post, spoke with Randy there a bunch as other have, he is very knowledgable on the lights he sells. last time i spoke with him he was getting in replacement batteries for the wizzard which were about 20 bucks. on thing he did tell me about the wizzard, i wanted to order some more expensive bulbs to make the light brighter but he said it wasn't worth it because the retro on the light would not allow the bulb to get any brighter that the cheaper bulbs were just as good. i have been using the wizzard scope light on a broom handle and it seems alittle bit brighter than the headlamp, so the one without the retro might be a brighter light.
