If it came close to the DEFT I'd be shocked, but I'd like to see it. I got some of the optics (from LEDsupply) to test on XM-Ls, but it yields an ugly beam. It wasn't until later that I found the link in my last post and saw the beamshot and numbers using an XP-C.
Somebody could also try one of the fairly new R4 XP-E and see what it does. I have neither the skill, nor permission (from the wife) to take on any new flashlight projects. :p
