Powerful little light! - Streamlight ProTac 1L-1AA Ultra-Compact Flashlight

First off, this light is a perfect size for pocket carry. The two way clip makes it easy to carry up or down. There are no sharp edges to wear at your pants as some other tac lights have. Whether slacks, jeans or even purse carry for the ladies, there's no situation it's inconvenient to carry. It's also really bright. The high setting default is the most useful. Being able to change the sequence of the Hi/Strobe/Lo is a very cool feature, too. The on/off button click is kind of deep so quick click on takes a definitive poke instead of a quick pop with your thumb, but this also will keep it from being bumped accidentally, turning on the light and revealing where Mr Flashlight is sitting in the theater or just discharging in a purse. The strobe feature is really useful to disorient anyone in a defensive situation at night. I hardly ever use Lo level but only because the high is first on and useful for the few seconds I need the light. If I needed it on for a really long time, I'd use the lo setting more. Awesome product!
