Cyalume Yellow Emergency Glow Sticks - Premium 6” SnapLight Survival Glow Sticks with 8 Hour Duration for Use as Emergency Flares and Hiking Safety Gear (Bulk Pack of 20 Safety Glow Sticks)

These glow sticks are great, and they have a million-and-one uses. I buy a box of 20 light sticks every year or two, depending on how quickly I use them. I keep them in drawers throughout my house, in case of a sudden blackout. You can never find a flashlight when you need one (especially in the dark). These are inexpensive enough that you can keep one or two in every room of your house for emergencies. I always keep a couple in the glove compartment of my car, a couple in my household first aid kit, and several in my disaster preparedness kit (a.k.a. bug-out bag). They always come in handy during Halloween for trick-or-treating, and exploring corn mazes after dark. They're useful (and fun) for any kind of activity after dark... parties, camping, music festivals... you name it. They glow for a long time, and generate a reasonable amount of light. This is a "must have" item for everyone.

I'm deeply satisfied with the price and quality of these glowsticks. I bought the box of 24 so I could have some on hand for emergencies, but I have three kids too so I broke open three of them and passed them out. It was a good test for brightness and utility as we turned out all the lights and the kids ran around the house with them. You can read with the light from these sticks, and you can see enough of the area around you to safely travel or find what you're looking for. I don't think you can ask for more from a plastic tube full of chemicals. The yellow sticks are fairly comfortable to read by, I suspect that might not be the same result from some of the other colors. Over time I'm sure my kids will use these up, once I get down to 12 or so I'll buy more. There really isn't any better recommendation than "I'll buy more of those." so I give these 5 stars.

I buy these every spring to keep around the house during hurricane season. I’ve lost power a few times over the years and these work great around the house to give some light to each room. They don’t give off a ton of light, but it’s sufficient to light up a small bathroom. Or use a few for larger rooms. One year I started giving these out on Halloween to trick or treaters. I figured, rather than wondering if they would expire and/or lose their strength the years in storage, I could give them out on Halloween! It lines up perfectly with the end of hurricane season. I keep a few just in case but they’ve become a hit. I think the kids like them more than the candy!

Definitely expected it to be way way brighter it’s just a normal glowstick frfr

We've used these every time the power has gone out. They're bright enough to skip using a flashlight and nice to leave in a bathroom and hallway for lighting in an emergency. I haven't timed them for the 12 hour duration claim but imagine that if they do last that long it'll be pretty soft light for the last few hours. The 2 to 4 hour power outages we've had weren't long enough to notice much of a dimming so they're a great addition to our emergency kit. Lighter than flashlights and no worries about burned out or broken bulbs or you're batteries going out. I've watched enough monster movies to know you should never rely on a flash light ;-)

I’m going to give the product itself a five star only because I’ve used Cyalume brand sticks before and I know they are a quality product for marking, signaling etc. The only thing I’m not a fan of is his they were shipped. They were just in a plastic bag with no protection. The only way to know if a chem light was activated due to being bent it impacted during shipping is to open all the chem light packaging which is something I don’t want to do. Fingers crossed on none of these being activated already.

After frequent power outages these have been a perfect little extra. They put out enough light to get around the house in pitch black, but work equally well outside. Parties, fun with the kids, or even emergencies make these a great little stowaway item. life expectancy is around 8-12 hours.

Cyalume makes great snaplights and I have been using them for years. If you are looking for snaplights for emergency use, these are the ones to have. I usually keep 20-30 on hand at all times in yellow, green and red.

I’ve used Cyalumes in the military for 20+ years. I know what they should look like when cracked. The vials inside this batch were discoloured before being cracked, and once snapped and shaken, they barely glowed. I could hardly see them in the dark from 5 yards away. Faulty batch, and seller didn’t respond to emails

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).

Bright. Easy to carry. They actually lasted more than advertised. Good price. Overall, happy with this purchase.

Gives off a decent amount of light and honestly I think I'm probably getting 14 hours maybe even 16, not quite as bright as the green ones but still useful.

I've bought these a few times, they're a great product. Same quality as used by the military. I use them mostly as night lights for my kids on camping trips or during power outages. Way cheaper to buy in bulk rather than 2 packs at camping stores.
