Product Description

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 has up to a five-year shelf life from date of manufacture.

The durable, waterproof, external body of the light stick is made from low density polyethylene (LDPE), and is phthalate free for safety. The internal illuminating chemical substance is non-toxic and non-flammable, and the components of the light stick are recyclable. The light stick floats in water and works best between 40 to 80 degrees F (4 to 27 degrees C), and although the light stick works at higher or lower temperatures, it is less effective in colder temperatures.

All sticks are tested at a temperature of 72 degrees F (22 degrees C) to determine the illumination duration. Each 10-degree C (50-degree F) increase or decrease in temperature doubles or halves the reaction rate, and therefore the brightness and duration. For example, the same light stick that emits approximately 30 lux (a unit that describes how much light is visible over a square meter) at 15 minutes after activation at 24 degrees C (75 degrees F) will be half as bright but glow twice as long at 14 degrees C (57 degrees F). At 34 degrees C (93 degrees F), the same light stick would be twice as bright, but glow half as long. Storage at elevated temperatures (above 120 degrees F or 49 degrees C) will decrease shelf life and start to soften the plastic tube, and increase the risk of a leak. Exposure to cold temperatures will not affect the light sticks if they are warmed above 40 degrees F (4.5 degrees C) before activation, unless they are frozen (which occurs at -15 to -20 degrees F, or -26 to -29 degrees C). Once light sticks have been frozen, they will still produce some light, but performance will not be as reliable. Humidity and atmospheric conditions do not affect the light sticks.

Light sticks are chemiluminescent substances in plastic tubes that provide hours of illumination in a number of safety, industrial, and military applications. Light sticks are waterproof, non-flammable, and non-sparking, which makes them useful in hazardous situations where sparks or flame could cause an explosion. Duration is determined by the chemistry of the formulation. Brightness is affected by temperature: the warmer the temperature, the brighter the light will appear. Viewing distance can be affected by temperature, moisture, and other elements. Exposure to direct sunlight can reduce shelf life and effectiveness.

Cyalume Technologies manufactures chemiluminescent products used for safety, industrial, and military applications. The company, founded in 1970 and headquartered in West Springfield, MA, makes products under ChemLight and SnapLight brands. ChemLight products meet military specifications, and the company meets ISO 9001 standards.

5.0 out of 5 stars Top of the line chem-sticks December 5, 2011
Verified Purchase
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.

5.0 out of 5 stars Great for emergencies or camping December 9, 2010
By DeusEx
Verified Purchase
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...

5.0 out of 5 stars Great in power outages, safe for kids April 2, 2012
Verified Purchase
I always keep Cyalume snap light sticks in the house for power outages and sleepovers. We've had every color, but we like these yellow ones the best. The white ones are our second choice, but their light doesn't last as long. The yellow ones last up to 12 hours and we haven't had any "duds" in the pack. We bought some of the cheap ones at Walmart once, and half of them had either been snapped at the store, or they were duds. Since you won't know if they work until you snap them yourselves, it pays to avoid buying them from stores where people can handle them.

These snap sticks help take the scary out of the dark - I give them to our kids when they have friends sleeping over, or when they sleep out in the yard in the tent, to save on flashlight batteries.

Because they're sealed and basically unbreakable, and they don't get hot, they are safe for kids to use unsupervised. From a power outage standpoint, they're safer than a candle or a lantern for getting around a dark house. We give one to each kid when the power is out, and it helps them feel secure and able to sleep in their own beds. An added bonus is the hole at the end, which allows the user to attach a lanyard and free up their hands.

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.


Instant emergency light that can be used in almost any type of environment.


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

5.0 out of 5 stars Bright Lights October 17, 2012

Nice Lights. Brighter than the ones you can get at most stores. Lasts 12 hours at full power, but up to 24 total even though it loses its brightness. No complaints, works to expectations.

4.0 out of 5 stars Good product February 5, 2013

Got this for our emergency kit. Read that it's a good idea to have one in your bedroom with a front-door key attached in case of fire or other emergency - then you can throw it out the window and notify emergency personnel where it is.

5.0 out of 5 stars Bright as any other May 21, 2013
Verified Purchase
I have used all colors of the cyalume line and have to say that the yellow is one of the top 3 to use a true light source. With this being my third choice it has more of an even tone from break to end. the other two I recommend is green and white. while the green stays bright for many hours, the white stays just as bright for the first two hours or so and then starts to decline hour after hour.

We purchased these to add to our emergency preparedness kit, but tested one first and lasted 12 hours and then some. Exactly what we needed and a great price, too.
