Class : Apprenti Posts : 2 Registered on : 15/10/2008 Off line	Thanks for the quick replies. Since Im not sending them back.. I figured I would try them out anyway. I made a quick circuit with a 9v battery and resister hooked to one of them, and it seems to be working great. So what would be the downfall to using them? Will they burn out quick or what? ps- Edited by Riserburn on 15/10/2008 at 23h23.
