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

Good to have in emergencies when the power goes out or to take camping

Works exactly how it’s described. Great for marking campsites

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.

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.

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.

Perfect for marking the way for night travel on camping paths

These are not the military grade. Military grade are hexagonal or octagonal to dissuade rolling and have a gated clip. I don't care, but be warned if it matters to you.

Great for Markings trails. Bobwire.. vehicles
