Default Re: NUBM07E 465nm Mace of Doom build

I'd like to modify the one I have to take 26650 or 32650 batteries if someone would make a tube with the right sized threads to screw into it.

Edit: Buy another one to mod: http://www.dx.com/p/small-sun-zy-a63...1#.VeZdbJem1NI

I'm totally going to buy that one. I'm pretty sure someone can make me a nice heatsink for it. Thanks. I like the 18650 tube a lot because it's so small. It really looks like some sort of mace haha.
