Cyalume-9-08005 SnapLight Orange Glow Sticks – 6 Inch Industrial Grade, Ultra Bright Light Sticks with 12 Hour Duration (Pack of 10)

Solid chemlight, is definitely bright for 12 hours, was visible from a short distance even after 36 hours. I use them to mark tents or when climbing at night.

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.

(Color: Red) Not bright enough to see anything in the dark, even only a foot away. However, it glows for a VERY long time (~20hrs), definitely long enough to last the whole night. I think it is most useful for highlighting certain things in the dark. For example, you could attach it to your backpack to find it quickly on the campground at night. Or attach it to the front door of the restroom to distinguish it from other doors. Things like that.Shelf Life: 5 years from the date of manufacture. In my case, it was about 4 years 7 months from the time I received it.

I have carried Cyalume light sticks in my survival and emergency gear for years. I refuse to buy other brands because in an emergency I need light that works the first time, every time. If there's a gas leak after a storm I want a non-sparking, safe light so I can go turn off the main. If I need to mark the location of someone who is injured I want a bright marker light that I can deploy in any context. Snap lights fit that bill and I don't think it's worth skimping on price when you need reliability.A few days ago there was a power outage and my wife pulled out two red snap lights from our emergency gear and cracked them. They lit right up and were nice and bright. But later that night I noticed that they seemed to have faded more quickly than I anticipated (our power was back on at this point).I logged on today to discover the reason why: the red snap lights were part of an order I originally placed in 2011. Yep, eleven years ago. I had missed rotating them out with my other purchases.11 years in storage and they lit right up and were bright to start - just no legs on them. I consider that a testament to the quality and durability of Cyalume over other brands.As long as they are in business, Cyalume will be the brand I carry for emergencies. I recommend you do the same.
