Should be able to see from space

Always went with SureFire. I decided to give Streamlight a chance at half the price and glad I did. The 10tap feature is great. Right now if I tap once 400 lumens, tap twice 1000 lumens, and press the clicking it on permanently gives me 1000 lumens. It does have a strobe function which I don’t use. The holes line up to most SureFire accessories. It’s mounted to an Arisaka offset mlok mount rather than adding a section of picatinny and using the included 1913 mount. It’s nice to be able to project 400lumens to conserve battery life because this will chew through em. Would I take it into a life or death situation probably not, I’d stick with SureFire. For my needs it’s perfect. Crazy bright and built like a tank. I d definitely buy again and recommend.
