Cyalume SnapLight Yellow Glow Sticks – 6 Inch Industrial Grade, Ultra Bright Light Sticks with 12 Hour Duration (Pack of 10) (9-08004)

Received these the other day to add into my hiking pack and decided to test one out first. First off, the package arrived intact and dry. No leaks from any of the sticks and they were all intact (not pre-snapped). I cracked a good stick at 6:30pm and shook the scrap out of it. It lit up like, well, a glow stick. If you're expecting to light your house up with one of these you're probably going to be upset, unless you live in a tiny house, then it might. Anyway, went to bed and woke up at 5am for work. The glow stick was still glowing bright without any real difference in brightness. I go to work and get back around 6:15pm and the stick was noticeably dimmer, but still glowing at a pretty good clip. Fast forward to the next morning, the glow stick is still glowing a dull yellow. It wouldn't light up much of anything, but in a dark search and rescue situation, someone might notice it.Overall, I'm incredibly happy with this product, worked like it said and then some. The casing is pretty sturdy. It glows a bit brighter than a candle without the worry of burning your tent down and lasts well past the 12 hours the package claimed.

Took these on a African Safari where I lived in tents for 2 weeks. I would light one each night at dark and they gave the tent a mice warm glow with just enough light so I could get around any time of night, still burning bright in the morning and still a slight glow 24 hrs later. They made the stay in the tent more convertible and they did not attract bugs.

These are top of the line light sticks. I used cases of the military version in the Army and these are the same thing made by the same company just the civilian version.The civilian version (SnapLight) is better then the military version (ChemLight) as the civilian version has all the latest composition and chemistry updates allowing for more brightness and shelf life longevity (5 year as compared to 4 for the ChemLights). This is because ChemLights are required to meet a DoD standard that locks them in to an older chemistry configuration.I keep them in my camping and emergency kits.If you like the review, click the Yes button below :)

I purchased these in 2012. And kept them attached to the outside of my med kit.The med kit is in my car and has been since 2012. In Los Angeles with heat going easily into the 90 degrees F in a car.The light expired in April of 2016. Last year exactly. I openeone up and cracked it. Still works!5 years in a hot temperature climate in my trunk.It was not inside my bag, it was attached outside of it, getting all the temperature fluctuations.The dark picture was 15 minutes after cracking it.It didnt light up the room but it will help you find the light switch if you hold it 1 1/2 ft or .4572 Meters.It did well for surving hot car temperatures for 5 years and 1 year past its expired date.Im getting more.

There really is no replacement for Cyalume chem/glow sticks. Many other glow sticks work well, but don't have the brightness or the longevity of this brand. In context to other Cyalume glow sticks, these are not as bright as the green ones, but serves it's purpose well. I normally use green for general use (camping, backpacking, power outages, etc) and yellows more for a "warning" or "caution", as I did in this case. On a side note, orange or red does not create enough light unless it's really dark. I would highly recommend this particular band. That being said, yellow is not ideal if you're looking for brightness.

After driving & coming around a mountain curve one night and almost running down a man in the dark road by the edge of a cliff who was desperately trying to direct traffic around a stalled vehicle to avoid a multiple car pile-up, I feared for his safety & wished I had something like this in my glove box that I could just hand over to him & help him to be more visible for his own safety. I know my husband is the type of person to also do something selfless like this to help others despite his own personal safety risk, so I quickly got online & purchased these. Now we have them in all our vehicles, along with reflective wrist-wraps & shoulder-to-waist banners (like the school crossing guards tend to use). I threw in some emergency thermal mylar blankets for good measure, because they fold up tiny & thin (just a few inches) & can go in the glove box. Now I just need to get some of those flares that work similar to sparklers that you can just toss onto the road to alert people's attention to an emergency, and we should be better ready to help out next time. That was a really scary moment that could have ended very badly.

My experience has been that most of the 12 hour Cyalume products do exactly what they are advertised to do. I have used them for night SCUBA diving, cave and cavern exploration to include underwater, and in hazardous atmospheres as a primary light (non-flammable) and they produce light with almost no heat. Easy to initiate after removing the wrapper by simply cracking the vial inside the large vial and shaking. Disposal is also easy as the chemical reaction eventually dissipates and and all that has to be done is throw them in the garbage. Keep in mind that there is no "ON/OFF" switch. Once activated they will run their course to depletion. Cyalume SnapLight Yellow Glow Sticks - 6 Inch Industrial Grade, Ultra Bright Light Sticks with 12 Hour Duration (Pack of 10)

I use these for Scout camps so the kids can orient themselves at night. I had assumed 12 hours/overnight, but when I've gone back to put fresh SnapLights the following night, the previous night's sticks are still glowing (and when I threw them all out at camp closing, there were ALL still glowing pretty brightly). These are fantastic, and I keep a supply on-hand at all times. Price is good for what you get.

Buy these mostly for power outages but sometimes when the kids have sleepovers I pass them out for night time fun (though there are certainly cheaper options, you get what you pay for in terms of how long they last and how bright they are). They really do last and give off a good level of brightness. So far I have tried the Yellow (favourite for brightness), green (kids favourite), orange and blue (blue does not throw much light but has its purposes).

Very grateful for discovering this product. It does what it's meant to do--provide emergency light, very bright I might add, when needed. I didn't want to waste one light stick for this review but in all fairness to this review, I did just that. I'm glad I tested it out, because now I know what to expect when I need to use them in an emergency. Great quality in this product and peace of mind, knowing it has a long shelf life. Thank you for keeping the price point affordable. My order arrived quickly, in just 2 days, and the packaging was secure. I highly recommend!

These are definitely your best buy as opposed to paying 5 or 6 bucks for two at Canadian Tire or Walmart.Used them for camping and they worked quite well as nightlights around the site. They even still had some power to them the following night after using them.
