The Cyalume ChemLight is an orange military grade chemical light stick measuring 6" long, for providing instant ultra-high intensity 360 degree illumination, that can be seen up to a mile away for up to 5 minutes in optimal conditions. The ChemLight 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. The ChemLight meets Defense Logistics Agency (DLA) and NATO Maintenance and Supply Agency (NAMSA) specifications, and National/NATO Stock Numbers (NSN) are printed on each product. Each light stick is individually foil-wrapped for protection from light and moisture, and has up to a two-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. All sticks are tested at a temperature of 72 degrees F to determine the illumination duration. 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.

I purchased the Cyalume 30 Min High Intensity Sticks but those were any thing but high intensity. Compared to the Cyalume 8 Hour in the same color, it was the same intensity.
These are the brightest light sticks Cyalume makes. If your going for duration use the 8 hour, if your going for intensity use the 5 min. In my opinion anything in between is just junk.
But just because it says 5 min does not mean it goes out in 5 min. It actually puts off the most light in the first 5 then dims to about an 8 hour glow stick then becomes useless after about 1 hour.

Not SUPER DUPER bright
Has a hook on the end (not a big deal, just annoying because you have to cut/bite them off...they tend to tangle on the laces)
I have handed these to EMT's at night in festival crowds so their colleagues can find them quickly.
Lighting these in a crowd immediately grabs attention. I can see why this is used to signal helicopters.

I bought these light sticks not expecting the best, since it had mixed reviews. I was surprised by how good these products are. Read morePublished 26 days ago by Kam Domber
Not as advertised-unsure if it's gross misrepresentation or willful ignorance.
These are the orange 12 hour sticks, not the 5 minute ones.
Bright and they burn fast - just how we like them. Ill usually wait until the crowd starts the thicken and then BAM - its like moths to a flame and your the center of attention. Read morePublished 7 months ago by Richard Wilcken

Pretty good. Very bright the first 10 minutes and stayed fairly bright for an hour, then slowly dimmed. Still a glow left after 6 hours, then I fell asleep.Published 12 months ago by William Schroeder
Sticks are marked exp 10/13- So use fast and pay less if you are smart. Ordered 5/14.. They work but not for long I suspectPublished 20 months ago by Charles H McCullough
These are plenty bright enough to spot at a distance or find something in your trunk but I wouldn't say they are comparable to a burning flare at all. Read morePublished 21 months ago by Mike Chronley
