I'm new to these. I went to the sportsmans warehouse store. I saw the Surefire,ED2 I think it is. The defender, with the skull crushers. it was 120$ I kept looking around and found the storebrand. it just says sportsmans warehouse real small.and olive drab color. it was only 30$. it was about an inch or 2 longer than the ED2. and it Also had the skull crushers on it. it was 3 watt,2 lithium batteries.L.E.D.. it has the bright first click and a dimmer second click. it's waterproof too.So my question is, does lumens mean how bright it is? Cuz this sportsmans wharehouse light with the skull crushers on it says 75 lumens with 4 hours. it's so bright if you shine it in someones eyes it'll blind them worse than a camera flash. But are lumen brightness. if so this light for 30$ is as bright or brighter than the 100$ ones. Anyway whatever it is it was a really good deal.
