First time ever I'll say I'm nearly ashamed to admit that I have a few thousand dollars "invested" in Surefire flashlights. I'll keep this short and to the point: I bought this light: http://www.meritline.com/focus-zoom-lens-cree-q3-flashlight-torch-light-lamp---p-66230.aspx It showed up from China today. I put in some no-name SINGLE AA battery and I shined it on my hand and I was temprarily blinded. (Hmph -- that's why it had that little trianglular warning sticker!?!) I went outside, and this thing is, and I'm not kidding here, like a little Q-Beam spotlight in my hand. The bezel slides in/out to adjust focus. Kinda weird when focused to a tight beam, as it is a perfect square. It'll hold it's square shape even when the light is thrown 200 yards. I CANNOT believe so much light can be emitted from such a cheap, small device. If used beside my Surefire M3 with the M4 Turbo Head Conversion, the little Chinese POS wins, hands down! It'll be interesting to see how this thing holds up. I'm glad I bought two, because it is AMAZING!
