Cyalume Glow Sticks Military Grade Lightstick - Premium Green 6” SnapLight Emergency Chemical Light Stick with 12 Hour Duration (Bulk Pack of 30 Chem Lights)

I have had these CYALUME snaplights in my vehicle since 2018 (6yrs), and they still work. I live in a climate where it's over 100° in the summertime. They are of good quality, easy to use and small enough for a first aid kit, which is where I kept them. I recently bought some of these in red to use instead of flares for my vehicle. They're non-flammable, bright and much easier and safer to use than flares. If you're looking for good snap lights these are the ones to buy.

Still usable after 16 hours, it has been 17.5 hours, I went into the closet to see how well the illumination is and if it were pitch black outside it could be used as a trail marker. I was able to get enough light from it at 17.5 hrs to read a map.I will buy these always, I am surprised I have never found one that stays illuminated so long.

As an avid camper, I've always kept a pack of Cyalume Glow Sticks in my gear bag. On a recent camping trip, these Military Grade SnapLights genuinely came to the rescue. The night had set in quicker than anticipated, and our campsite was shrouded in darkness. Popping a few of these out, their bright green glow illuminated the area with a soft and eerie light, allowing us to set up our tents without fumbling. The 12-hour duration claim isn't an exaggeration – one lasted the whole night, serving as a makeshift lantern inside our tent. Having 20 in a pack means I can share them with fellow campers or save them for several trips. They're compact, easy to activate, and incredibly reliable. If you're ever in a pinch or just want some atmospheric lighting, these are a stellar choice!

I was hesitant about these lights due to I have experience with the military grade chem lights. I purchased these to get more bang for my buck, and man did they perform. These are just as good if not better, than the military grade lights. The only real difference is the design of the hook enclosure for attaching to wire or parachute lines. I took the picture during the day, under natural light, 17 hours after it was activated. As you can see, it is still visible. These are now my go to lights for emergencies, camping, and hiking. I don’t t normally do reviews, but this product deserves recognition for its performance and price point. Great Job SnapLight!

I bought these for casual use. Camping and grandkids Halloween / playing in the yard. I am not qualified to comment on their "military grade" claims as I never used chem sticks when I was in the military. But I can say these sticks appeared to be brighter / last longer than the ones I've bought at the local dollar store.I am writing this review a few years after purchase but at the time I was satisfied with what I paid for what I received. I would buy again if I needed them but grandkids are now older / live in a different state.

Military grade lasts at almost full power for 12 hours as advertised and 24 hours later still has a slight glow.

I've used several brands of glow sticks now, I keep some in my car for emergencies but we also use them for hunting and camping. These glow sticks are bright and illuminate the area nicely, they glow for hours. After about 6-8 hours they do seem to dim a bit but for our purposes these are fantastic! Will definitely be buying them again!

Perfect for marking the way for night travel on camping paths
