The Cyalume SnapLight is a orange industrial grade 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 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.

Great bear and mountain lion deterrent but attracts mosquitoes Bought these for my son and his friend along with a few other colors. They took them on a campout and had a blast playing games in the dark. When it came time to sleep, they all had their own new glowstick to use as a bear and mountain lion deterrent. They worked, not a single kid was eaten by a bear or mountain lion. They were, however eaten by mosquitoes.
Bright and long lasting light source – Bright, long lasting, safe and convenient light in a pinch, or snap – Not much to say – Cyalume has been around a long time and I’ve yet to have a problem with any of their products – They claim a shelf life of around 5-7 years if kept in it’s foil pouch, but I have used ‘expired’ sticks that have been subject to all sorts of excessive abuse in the back of work trucks, toolboxes, etc and they still fire up up bright like new – The one thing I will point out is there really isn’t a noticeable…
NOT A FLASHLIGHT REPLACEMENT I knew exactly what i was looking for with the intended purpose of these light sticks. The price listed from this seller is on par with local retailers, perhaps a few cents more expensive. once i placed the order (of which i purchased two boxes), it was a short two day wait until they arrived. No fancy packaging here, just a box shaped like a pencil box with ten individually wrapped light sticks in side. My package arrived with obvious bends in the box, i wouldn’t say crushed, perhaps…
