Emergency Glow Sticks - 12 Stuks

I purchased these awhile back and going through my hunting and camping gear yesterday decided to give one a test drive. We like to keep our house cool so it is approximately 65 degrees inside. At over 20 hours the light stick is still glowing and bright enough to read in a room devoid of other light (interior bathroom with the lights out). At this point you have to hold the light within a few inches of the reading material but still impressive for an emergency situation. Note in the description the cooler the temperature the longer the light glows (but not as bright). At a warmer temperature the light glows brighter but doesn't last as long. At this price point I think they are a good value. Hope this helps.

I just found (in 2024) one of these that I purchased in 2012. It had an expiration date of 2016. It cracked without failure and glowed as bright as a brand new one.

Useful in an emergency and convenient around a tent site at night. They give enough light for enough time to slurp down dinner and a cup of coffee or tea and then they slowly fade over maybe 8 hours. Just hang it from the gear loft in your tent as a night light. It won't be enough to keep you awake but it will allow you to see if you need to get up during the night. The ones I received are genuine Cyalume sticks with a "use by" date of 2021. I intend to keep them in the house as part of an emergency kit and I'll throw one in my backpack for each night I'm on the trail.

I bought a pack of these a while back and they have come in handy several times. During camping, power outage, gave one to a neighbor’s kid when they went out trick or treating to be seen. Have one in the truck of the car/glove box. They usually are good for about 5-6 years.

For less then a dollar a piece, you really can't go wrong with these light sticks. I keep a couple of them in my survival kit that i have in my vehicle. From what I've read, the green color light sticks are the best color and I'll take their word for it. The hook on it actually is quite handy, I used it to hang in the lean-to i built while camping in the middle of winter... worked well as a nightlight so i could see the entrance and the woods around me throughout the night to make sure no wildlife decided they wanted in. Also handy to tie around the neck with some paracord to keep track of people like small children, heaven forbid your children are ever in a survival situation with you. They do fade after a while but if you're going to complain about that than shell out some more $ for military grade light sticks and stop crying because the cheaper ones don't out-preform the more expensive ones. For me, these produce enough light for the intended purposePros- ''Glows'' for more than 12 hours... still ''glowing'' after 24 hours- Handy little clip on the top- Works in all climates/environments.... worked flawlessly in 15 degree winter weather- Great alternative/backup for flashlight, works while wet, no battery needed(5yr. shelf life), not affected by temp (within reason)- Durable.... took a few minutes of intentionally bending it in half back and forth to get it to break (non-toxin anyways)Cons- After 4-5 hours the lighting begins to diminish slowly, but is still usable in the dark up to 12 hours- No sleeve to protect it from bending accidentally, i may find some thin pvc to use as a sleeve
