I have several BOWLITEs ( white, green & red) for hunting and bow fishing and you can't beat them. Really, I am tough on any equipment and they keep up with my abuse. They come with two lithium batteries and I have yet to kill one. Also comes with a dual charger that you can use on the wall plug or cigarette lighter. I LOVE, LOVE mine and so does my hunting partner. Thier site is
www.thebowlite.com Oh and different mounts for anything. One that is a double scope ring 1", and another that wraps around with a velcro type mount, and for the bow, they attach in the stabilizer bar hole. has dual modes in low and bright and two kinds of switches. A pressure switch and one that you just click on and it stays till you click it off. Good lite and good people at that company. I'd post a picture of the set up if I knew how.
