I've got two TLRs, a "1" and a "1s". Both are great. One rode my duty gun for a while with no issues. Personally, I can't imagine ever wanting a brighter light on a pistol. If anything, it's occasionally too bright. The light would be perfect for me with an additional mode at 50-60 lumens or so. One of my TLRs is currently on my patrol rifle and it's easily bright enough for target identification out to 100 yards. I have several handheld lights in the 500-800 lumen range and I can tell you from direct experience turning one on indoors with your eyes adjusted to complete darkness is NOT a good thing, at least not for me. Outdoors, game on.
