The Ultrafire C1 from DX.com, 28mm optic lens from DX.com, 9v xenon bulb from DX.com. May I know what type of battery it use? I have 2x Trustfire 3.7v 16340 batteries. I use it on the (http://www.kaidomain.com/Product/Details.S000905) and it burnt! Can I know what battery you use on your xenon burner? 2x 3.6v or 3.7v 16340 battery? Can I use 2x 3.7v on it without any problem? Sorry for lot of question and thank you.
