I found this the other day and I know alot of members here look for something suitable for a weapon light build.here's the link http://www.intl-outdoor.com/amc71358-1mode-circuit-board-nanjg-105c-p-643.html it's based on the 105c board and should be a ready to go solution for those building a p60 module for a gun light.It's drive current is 2.8a,so it would be good for xml and not drive too hard to preserve battery life.Just thought I'd throw that out there.
