I was up late a while back watching some good guns and gear vids on youtube and came across a review on the Quark AA2 Tactical light. So on a whim I ordered one from 4sevens. I had never carried a flashlight before and also never thought I needed one. A Mag-lite in various sizes has always been my flashlight of choice. I've got one in the house, cars, dump truck at work, they are all very handy. I hadn't gave much thought about an EDC light before my Quark arrived. Boy is this thing handy. Small, lightweight, reversable carry clip, two programable modes, super bright on turbo, also super dim on moonlight mode which is useful. I have had it in my front pocket everyday and I think it makes a great companion to my other daily carry stuff; Glock 19, Benchmade Mini-Griptilian, and cell phone. It's sort of ironic how I use it all the time like working on my cars to finding something I've dropped, to coming home at night to find the porch light off. I've actually used it so much in the short amount of time it is already dinged up. The other day I was at Fry's Electronics and found a Fenix LD20 and bought it. I don't notice any difference in brightness really, pretty much like the Quark. I do favor the Quark because the clip is reversable by switching the tail and emitter around, also sits lower in the pocket. The Quark (tactical model) has a momentary on function that I love and two programable modes by twisting the emitter head. The Fenix is by no means a slouch though, its just a diferent UI. I have gotten used to it and would be comfortable with either one so I'm not saying the Quark is better just different. Anyway, for those looking for a good cheap (compared to USA brands) flashlight you should check out the Quark or Fenix lines.
