This light is packed with features, strob, batter low warning, finger ring built in, adjustable on brightness.... I did my home work on 123 LED lights, this is the one I choice, and I'm not sorry.

I am a police officer who works nights and I consider my flashlight one of my most important tools. This light is great. It has an incredibly bright beam, and though it isn't adjustable, it casts a great tight hot spot for good distance, and a nice wide outer ring for flooding a room. The strobe is great for signaling and blinding an opponent. One of the best purchases I have made for work in a long time. Since I got mine, numerous other officers in my PD are buying one now. I worried about durability with the electronics in this light, but after numerous drops now it has held up fine. I have owned high end lights from Surefire and Streamlight and none have performed or lasted like this one. If lighting at night is more than a convenience and your life may depend on it, give this light a try. Tip; it is the same light as the Gladius but for less money.
