Industrial Versus Military Grade
These simply work. Used them extensively in the military.One thing I will add to your purchase consideration: the Cyalume SnapLight "Industrial" Grade Chemical Light Sticks lights are chemically very similar to the "Military Grade", but with a longer shelf-life. The "military grade" lights are formulated per DoD specification, and as such cannot take advantage of newer formulations.In short: if you are buying the "Military Grade" lights because you think they are better somehow, they are not. They are the same brightness. As a matter of fact, according to the manufacturer the military versions have one year less shelf life (4 versus 5 years for the industrial series). The higher price reflects the custom (older) formulation that the DoD specifies.Source for this info: Cyalume Corporation.So unless you are required to buy an NSN product, do yourself a favor and pay less for a longer shelf-life and get the industrial version of this...

Long lasting, safe for kids
I always keep some snap light sticks in the house for power outages and sleepovers. We've had every color, but these white ones are the best. They last a full 8 hours and we haven't had any "duds" in the pack. The white light glows brighter than red, yellow, green, and blue, and help take the scary out of dark rooms. I give them to our kids when they have kids 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. An added bonus is the hole at the end, which allows the user to attach a lanyard and free up their hands.

Product Description
The Cyalume SnapLight is a green 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.
