The Cyalume SnapLight is a yellow industrial grade chemical light stick measuring 6″ long, for providing instant 360 degree illumination, that can be seen up to a mile away for up to 12 hours in optimal conditions. The SnapLight is waterproof, non-toxic, and non-flammable. To activate the light stick, bend, snap and shake the tube. The light stick has a hook and gate top, for hanging or attaching the light. Each light stick is individually foil-wrapped for protection from light and moisture, and

Great for emergencies or camping,
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…

|Top of the line chem-sticks,
These are top of the line light sticks. I used cases of the military version in the Army and these are the same thing made by the same company just the civilian version.
The civilian version (SnapLight) is better then the military version (ChemLight) as the civilian version has all the latest composition and chemistry updates allowing for more brightness and shelf life longevity (5 year as compared to 4 for the ChemLights). This is because ChemLights are required to meet a DoD standard that locks them in to an older chemistry configuration.
I keep them in my camping and emergency kits.

|Good for emergency use in harsh environment or Halloween, but costly,
Reviewing color: Yellow
At over a dollar each these are best for emergency use or as a safety light for a Halloween night. I tested one and for the first 15 minutes it gives off light equal to about 1/2 the light of a standard night light. For those roughly 15 minutes, you can read black and white about a foot away from the light source. After that the stick starts to dim to a low glow until the only visible light is of the liquid in the stick. Technically it will last 12 hours, but realistically the light stick is only useful for a short time under most situations. Unless you are in a harsh environment where flashlights won’t cut it, these are not a necessary item to have as a light source for most emergencies.
Pros:
Instant emergency light that can be used in almost any type of environment.
Cons:
Price, at over a dollar each there are longer lasting reusable light sources you can obtain for emergency use.
Duration of “useful” light much shorter than advertised
