I received one of these for Christmas, it's a combination light/laser:
Leapers, Inc. - Hunting/Shooting, Sporting Goods and Security Gear
I was pleasantly surprised to see the light was noticeably brighter than my Surefire X200. I was hoping I could get you the part # for just the tac light part, but the part # is for the whole kit. Maybe Leapers could tell you what part # the individual flashlight is if you're interested.
