The Cyalume SnapLight is a green 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.

Same great quality Iâve come to expect! I had just let my kids use the last of these for a sleepover. They were at least 7 years old! They put out an awesome amount of useful light for at least 12hours. They actually stayed illuminated for approximately 16 hours. So I ordered more from Amazon, and when i received these, I was equally as pleased as I was with the ones I was replacing. See attached images for packaging and lot number/expiration dates. I would definitely purchase these again. I will update after using about 50% of the…
Bright little gems that last for hours! These Snaplights are great. As soon as I received them, I turned off all the lights in my house which made my house pitch BLACK, as I live in the country. I couldn’t see my hand in front of my face. I took a couple, broke them, and sat them around the biggest room in our house and they lit up the whole room – that’s 22x 17. They provide enough light to let you see what you’re doing. I know the grandchildren will love them when we have the next campfire. i had seen other children running…
Inconsistent I bought a 10-pack of these a few years ago for emergency use and they were fantastic, so when they ran out I immediately ordered more. The second pack was terrible; I tried three different sticks and none of them gave out enough light to be useful. I had one stick left over from my first order so I lit it to compare with one of the new ones, see the attached pictures. Both of these sticks were cracked within minutes of each other, and the pictures were taken about 15 minutes after opening…
