Product Description

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.

Wow, now this is what I call a glow stick / light stick!

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.

I use these to glow string with. First off these are very bright and they last a while. They are ultra bright for about 5 mins but for the next 45min to an hour they fade but are brighter than the average glow sticks. I stopped buying these for now because they are a bit pricey for me. They have dropped the prices on them so I am considering buying them again. Anyways as I said these are very bright and last a while. The only other brand of glow sticks I have seen brighter are the Revolutions. However Revolutions burn out faster and are less durable. Revolutions always break on me when i wrap or do orbitals. The Cyalume are very very durable. It is not often that they break on me when i spin. Before you spin make sure to cut off the hooks at the end so you dont get your laces tangled. :D

PROS
Very bright
Last a while
Durable

CONS
Price
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)

Threw a box of these on a crowd of 2500 at a cruise ship music festival. The result was incredible.
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.

These are certainly brighter than average, but when compared to snapflare alternatives by Cyalume not nearly as bright. The snapflare simply contains more volume and thus appears much much brighter than these. Not only is the snapflare 2 inches longer, they are also thicker diameter and let off much more light. I rave and prefer to spend my money in the snapflare which provide a much bigger wow factor.

I've seen some BRIGHT glow sticks, and they may have been this brand, but if they were they were soaked in boiling hot water to increase the speed of the chemical reaction that creates light inside glowsticks. For emergencies like a breakdown on the side of the road these are great for drawing attention that normal flashers would not attract, and are safe as they do not generate any heat. I'd keep looking though if you're just looking for incredibly bright glowsticks.

I bought these light sticks not expecting the best, since it had mixed reviews. I was surprised by how good these products are. The luminesce very well for the first thirty minutes: much brighter than the regular grade ones. What really took me off guard was that they continued to glow, at a reasonable level, for a couple more hours. Yes, these do wear down more than one of their normal light sticks; but this would be much better for like a short roadside emergency. I would definitely buy these again.

These light sticks function exactly as advertised. They are much brighter than traditional light sticks but last for a much shorter time. The light itself will continue for several hours, but only the first 5 minutes or so provides the bright light. This would be great for signaling purposes over long distances when traditional electric lighting is not desired or is unavailable.

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. packaging is sturdy, I've never had one arrive already cracked and the little loop at the top is handy for attaching to your clothing. They fade out slowly over about 10-15 minutes but do give off some light for a few more hours, although nothing like the longer lasting glowsticks from the same company. I bought a set last year to help my group meet up at music festivals at night and had some leftover for this year. They worked fine and didn't appear to suffer from sitting in my car for several weeks out of their box but in the foil wrapping. If every lumen counts (glow stickers I'm looking at you) these are the brightest I've found but for most purposes I would probably recommend the longer lasting ones by the same company.
