Quick little mini mag that I really like. Done with a Nanjg 105c driver, xm-l u3, 20mm 30 deg optic, 1/2 copper pipe cap and a couple of copper pennies soldered inside the pipe cap for extra heat sink. I also used one of the little tail clickies. I like the tint of this light. Gets hot pretty quick on high. Here is a link to pics.
