Review on Stay Safe Anytime With Cyalume Yellow Emergency Glow Sticks - 10-Pack Of 6” SnapLight Survival Glow Sticks For Emergency And Hiking by Tim Wilson

So I wanted some decent snap lights for my car, camper, and home. You know the drill, the power goes out and the flashlight batteries are dead because you forgot to check them. No problem, you've got SnapLight by Cyalume. These put off a nice yellow light the is plenty to illuminate a stairway or small room. Two or three can illuminate a big one enough to see obsticles and people. So why by Cymalume rather than the "cheaper" brands. First off, they aren't that much cheaper. Seriously, $3? You'll waste that at the snack/soda machine today at work. Next the brightness and life. As I said, I personally opted for yellow. It's a pretty well known fact that humans see yellow light brighter than any other color, so it just makes good sense. Next these are brighter than the cheapies you get your kids at the fair. And finally, although they steadily loose their brightness as the chemical reaction rages on, they put off a stong ammount of light for about 3 hours and good light for about 7. By 11 their pretty dim. The shelf life on them is five years so it's a cheap investment should you not need them, but trust me, you will.
