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 product.

Hope this helps.

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.

I purchased several of these snap lights and white is not the color that you want. Within two hours after snapping a white one it is so dim that it is almost useless. Go with the green or yellow. Those ones were MUCH brighter and stayed that way a LOT longer !!

I have a habit of keeping some light sticks in my hiking pack and after Halloween I needed to get some replacements. After reading some reviews I decided to go with these. Let me say this, when you first snap them they illuminate greatly, but after about 30 minutes they are only good for markers(greatly reduced visibility). After about 2 hours they are completely useless. I am glad that I tested one tonight. I would hate to have been somewhere that I was planning on using them and had to endure the embarrassment of displaying these. I am very disappointed in the product and will be attempting to return them. I would not recommend these for anything or to anyone. Pure waste of money!

Even though these are Cyalume light sticks, they don't live up to the name. These are only as bright as the average light stick and the light fades away very quick; to a light dim after about 2hrs like someone stated previously. Even at its brightest, it can't even light up a normal sized bedroom. No doubt these will last up to 8 hours as stated, but the catch is that after an hour or two, they're dim, very very dim. From experience, orange/gold light sticks are the brightest of all the Cyalume lights, one of these can light up a hallway or large sized bedroom/living room.

These light sticks are the worst light sticks I have ever used. I don't care what the manufacturer says these are no more than path indicators!!
I have used light sticks for more years than I can remember. Having ran out, I bought these. What a surprise during Hurricane Sandy, as soon as the lights went out ( around 6 pm NYC time ) I went to my first line of backup. The light sticks.

My wife stood around as I opened the first one ( we use 2 at a time ) and chuckled after I cracked it and it came on. She said " you 've got to be kidding". The light was SO DIM I thought it was a defective. Not yet wanting to give up on humanity yet I cracked the second one.

A barely glowing tube of plastic.
What a disappointment.

Another family member I gave some to , called and asked if these were "seconds" I said no, but thinking about it they must have been old stock at best.

But since these are part of my emergency preparedness kit I won't be buying these again!!!
Can't take the chance.

My advice to you all is go to sporting goods big box store and buy them there. Same price and I have never had a problem with them..
If you want to know where the store's name rhymes with Rick's. Or the store that starts with a "C" or "B".

I would do a video review but the light sticks were to dim to film. And I have a low light camera!
Just my story, another story in this naked city of a thousand stories,,, Just my story.

I can recommend that this product works well in below freezing weather. Used them to mark a path, and even in 9 degree weather, worked perfectly well, and stay lit a bit longer than 8 hours listed.

Delivered EXTREMELY quickly from the merchant! I got it WELL before expectated!

I have to agree with the other negative reviews on this product --

The white color is cool, and these glowsticks start out pretty bright, but it fades within 5-10 minutes to a level that's scarcely sufficient to read by, even if you hold them inches away from the page.

You shouldn't rely on these for emergency lighting or use while camping. Even as a safety marker, they fall short because of the color (can be mistaken for moonlight shining on a wet leaf, etc.).

You're better off sticking with the yellow or green glowsticks -- these white ones just don't cut it.

I did quite a bit of research about these white light sticks,mostly by reading other folks reviews. I know some people can be supercritical about a product and others are merely amazed by the technology and think most things are just fantastic if they barely perform, I like to think I fall a little toward the optimistic side. So I conducted a little experiment ,I can see well in a very dark enviorment, have worked many years outdoors at night on power restoration for various utilities during outages. I purchased these anticipating use during a critical emergency, ie;auto breakdown,assesing wounds and providing first aid,seeing in totally dark areas, and as a crude replacement for a flashlight as needed. My testing showed that if you are not in a totaly dark area,get a flashlight if you need to see with any detail, the sticks I activated and used didnt give off enough light to perform many functions, Im sure you could read a book if you had to,but it wouldnt be very comfortable on the eyes for any detailed work, As a path marker they would function fine, 1 mile visibility, I doubt that ,would have to be some "ideal" conditions! I tried in several different temperatures, 34 F produced a very dim light, 72F was about optimum,but nothing impressive, so for a dollar apiece I think I could of went to Family dollar and bought a cheap flashlight and some cheap batteries and got better performance. I also tried the green ones, they appeared much more light under the same temperature conditions . one plus ,was that they did last for the advertised times, so Id say "dont expect these to be as bright as you may think they will be".
