Cyalume Glow Sticks Military Grade Lightstick - Premium Blue 6” SnapLight Emergency Chemical Light Stick with 8 Hour Duration (Bulk Pack of 10 Chem Lights)

I bought these light sticks to go in my bug out bag and vehicle. I bought ten red and ten white. I tried out one of the white ones last night.They're activated with the standard "snap and shake" like virtually all glow sticks. These take a little more muscle to break than a recreational glow stick. That's one thing I like, I feel confident carrying them in a bug out bag without fear of accidentally setting one off.The light produced by these allegedly white lights is actually extremely pale blue. The stick itself looks white, but the light it casts is obviously blue, similar to those blue halogen headlights or a poor quality LED flashlight. The light is fairly bright. In a dark room, I was able to easily read a typical paperback novel by its light. I recommend using the wrapper as a reflector to keep from exposing your eyes to the direct light. It makes the projected light appear brighter.These would make a sufficient emergency work light. If you had to read a map, cook a meal, or bandage a wound, these light sticks would be sufficient in a pinch. I would keep them around for power outages.The one I tested was still giving off a useful amount of light after 10 hours, so I'll accept as fact the 8 hour rating.Bottom line: These are the real deal. All preppers should have a box of these.

- I bought these for my Storm Emergency Kit. I prefer the white for my kit.- the hook is nice so it can be hung on the wall, or hung on a line- These work nice when camping / backpacking because of the shelf life.- The light output is ok. Remember folks these are not intended to be super bright (like a flashlight). Search for another product if you need that type of light output. These are for a glow that is good enough to make you seen, bright enough to read a map, and long lasting enough to glow most of the night.

What I received was exactly as pictured - Cyalume written on each wrapper.It's plenty bright for the purpose, i.e. emergency lighting. This is not a flare, but if you put it on a piece of string or paracord and swing it, you'll make a large visible circle of light, but you knew that.I also picked up a few "party" snap lights at local closeout store (they're gearing up for July 4th). Those come 2 per wrapper, are a tad smaller and were 3 double packs per $1. I grabbed some reds and blues. They work ok too, but perhaps not a substitute for Cyalume, which is larger, brighter and the hook is integrated.My guess is that the most useful colors are: blue (utility lighting, you could use green, but it makes everything look weird), white (bright), red (when you want to be able to still see in the dark, i.e. stargazing, camping, etc.)This is the best price I've found and everybody needs more than 1 - put some in your cars, backpacks, first aid kit, home emergency pack, etc.

The Cyalume White Emergency Glow Sticks are an essential tool for emergencies, camping, or hiking trips. These 6-inch glow sticks are lightweight, easy to activate, and provide a steady white glow for up to 8 hours. I’ve used them during a power outage, and they worked perfectly—bright enough to light up a small room without being overly harsh on the eyes.What I like most is how simple they are to use. Just snap, shake, and you’ve got instant light. They’re waterproof and don’t rely on batteries, which makes them a dependable backup for outdoor adventures or emergency kits. The bulk pack of 10 is also great value since you can stash them in your car, home emergency kit, or hiking backpack.The light output isn’t as bright as a flashlight, but that’s expected since they’re designed for ambient or safety lighting, not spotlighting.Overall, the Cyalume White Emergency Glow Sticks are dependable, easy to use, and versatile. They’re a must-have for any emergency kit or outdoor gear collection. Simple, effective, and ready when you need them.

I bought these and I love them! I throw them in my suitcase or back pack, in case of emergency. I have used them in many, many places. We used these in Maine in the woods when it was too dark to see our way to the path. They were great! We have used them in our hotel rooms as a night light. We like to place a few on top of our tent so we can find it easily at night, or we use them to light the edges of paths on many camping adventures. We have them at home in case the electric goes out during a storm. We snap them and place them on stairs or anywhere its hard to see without lighting. These snap easily, and with just a quick shake, they light up brightly. They last all night. I really love the white snap lights better than the color lights. These are bright and easy to see in the dark. They store well and are super easy to use.

I used these at an advanced firearms training event held through dusk and into the dark of night. They were used to mark the firing lines at various distances, as well as provide just enough illumination to see inside of range bags, diagnose malfunctions etc. without ruining our night vision. I've used other glow sticks that didn't last as long, but these lasted 8+ hours and were still going strong when we wrapped up. The red versions were used for similar purposes and worked equally well.

bright, easy to use, long shelf life, gave each of my friends kids and their friends one while playing in the dark behind the house... kids thought they were great and adults liked them because they knew where the kids were. great to keep in the car for changing a flat.
