I knew exactly what i was looking for with the intended purpose of these light sticks. The price listed from this seller is on par with local retailers, perhaps a few cents more expensive. once i placed the order (of which i purchased two boxes), it was a short two day wait until they arrived. No fancy packaging here, just a box shaped like a pencil box with ten individually wrapped light sticks in side. My package arrived with obvious bends in the box, i wouldn't say crushed, perhaps "stressed". Despite the exterior however, all ten light sticks in the first box i opened to test were in perfect condition. upon removing one light stick from the box, you will immediately notice how thick and strong the foil they are individually wrapped in is. Absolutely no light or moisture is going to get into this packaging without a puncture. I was particularly interested in this feature, as i intended to keep these around for awhile prior to use. i unwrapped the first stick, which was easily accomplished thanks to the perforated edges of the foil wrapper. The stick itself is bent to activate, i believe breaking a glass tube on the inside and releasing the necessary chemicals to create this chain reaction. When bent to activate, it initially felt like i was going to break the entire stick in half, but after applying enough force, that satisfy snap occurred and the light stick sprang to life with a bright orange light in my hand. Im not sure why these light sticks are labeled as industrial grade, but do not be fooled into thinking your buying a portable torch. they are bright enough to be seen for extremely long distances, but not really bright enough to use as a source of light to do things much more than 5 or 6 inches away from the light itself. If your going to use this for safety in mind, it should fit the billet. I give one to each of my three cousins when we go trick or treating, just in case they start wandering of the sidewalk into some dark yard. Spotting a glowing orange light is much easier than spotting a 7 year old dressed up as a fireman at night. Another useful way i use these lights is to mark where we keep our trash bag while we are camping. usually placing the trash bag outside of our camp (to keep animals from getting too close), we tie one of these up with the plastic hook on top to the bag, and bingo, easy to spot your destination. I imagine you could use them perfectly well for spotting things in the dark, but they aren't what your looking for as a flashlight replacement. The plastic tubes are sturdy, they are not going to accidentally snap, the foil wrapper is well designed and perfectly suitable to protect these light sticks, and the product is fairly priced. If your not fooling yourself into thinking that these sticks will turn night into day, im sure you will be just as satisfied as i was with this purchase.

I recently purchased these red chemlights for various outdoor activities, and I must say, I'm thoroughly impressed. Here's why:1.

These chemlights have proven to be reliable for extended periods, making them ideal for camping trips, night hikes, or emergency situations.3. Sturdy Construction: The build quality is commendable.

They've certainly earned their place in my adventure gear, and I'll be restocking when needed.

I bought the 10 pack in two colors - red and green. Based on reviews here, I went on the hypothesis that the green would be great for illumination, and red would be best for situations, such as night hiking, when I want to have a light but not have it affect night vision as much. After testing both the red and green, that is exactly how I would use these.Green: Very bright, would be great as a safe alternative to candles in the home in emergency situations (kids or pets can't knock it over and light the house on fire), or to provide illumination when hiking or camping. Would be great in the car as well for emergencies.Red: It's bright but really only provides bright illumination to itself, and not to its surroundings. It's best used as a location marker. I'd use it primarily when night hiking with other people and attaching it to their backpacks so its easy to note where they are. You could also use it when camping to mark key locations around you in the dark such as hazards and water sources. Because it doesn't illuminate its surroundings much, I think it would do a better job than the green at saving your night vision. It's use around the house in emergencies is pretty limited, probably only to mark things such as sharp corners.I activated both the red and green 12 hours ago and they're both still going. They're obviously not as bright as the first few hours but still usable. The plastic in these is pretty thick as well, and would definitely be OK with giving to kids without worrying if they'll break and spill out (even if it did, it's non-toxic).Overall, would definitely recommend these, but if you do use the red, know its limitations.

Pretty basic product as you'd expect, you crack them, shake them, and they glow. I've used two so far and they last for over 12 hours, although getting dim by the end. The same level of brightness of any other glow stick I've used. Good price, shipped fast. No complaints. Exactly what I wanted.

Lasted longer than I expected.

me sorprendió su duración y la intensidad, las recomiendo. No las he ocupado para emergencias, pero troné una para ver si funcionaban y salió perfecto.

Leuchtet 12 Stunden!! Hält absolut was es verspricht!!

Pack of 10 ordered via Contact Left Limited, delivered two days later. Genuine Cyalume products with a 4+ year use-by date (it is Feb 23 now and the use -by date is 06/27).Tested one: It took some force to snap the internal capsule, which is a good protection against accidental activation. Good red light visible from afar as a marker. Illuminates an area of about one meter. When held close to a page it is sufficient to read with. Started to fade after 13 hours.In my opinion, if you need one for a first aid kit, find a white one - there are high intensity 30 minute versions for such uses. If you need a general light, the red are best and do not affect your night vision quite so much.I only ever use Cyalume after I found that the cheaper products occasionally simply did not work when I needed them
