It's real small and light and I didn't want to add a lot of weight to my carbine.
I don't know if anyone has any experience with how durable these are but it's a nice little light. It's 70 lumens and I don't really see how anybody would want more indoors. Outdoors sure, but indoors. If I just paint the floor it lights up a room and it sometimes messes with my eyes if I look too closely at the spot, if it's reflecting closely off of a wall.
It also has 3 modes. And a button that can be clicked on, or momentary on. If you hit the button quickly twice, you get a strobe. And if you hit the button 3 times, you get a lower light. And if you click the button after any of that, it will stay on in that mode. Meaning if you click it three times, and want the lower light output to stay on, you just push the button down all the way and it stays in that mode.
I really like it. I don't know if they make mounts for such a small light, it's pretty dinky. It does use a AA battery but the body is still pretty thin. So I just bought some Gorilla tape and taped it to my M4gery handguards. I know, ghetto, but it's not going anywhere. I don't think.
It would be a good light for your pocket too. Although they make some even smaller...... My wife got it off of Amazon.
I'll get a pic up later but if anyone has any experience with these and wants to share, I'm all ears. I have no clue if it's to be trusted or not, but I figured it's streamlight.......
