1 mode driver board for weapon light use

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.

lupodrv has some tactical options, too (mode locking)
