Through in my backpack and car for emergency use

Yes! the pack i bought works well. of the 12 hour runtime i tested one and for 6 hours it was very bright and after that time it was bright/ well lit yet but faded to a slightly less bright then when 1st activated but did last for 13 hours. very pleased with the results. on another test i held one enclosed in my hand and another unit on the table that would go into a glass of icey water for a little while and out the unit held in my hand was much much brighter then unit in 1st test that was just on my desktop. both lasted 12 and 1/2 hours. Very pleased with the purchase.

I bought these, like... years ago, and they still work to 100% efficiency

Great if you lose power for a safer,candle substitute. I keep them in the vehicles as well and use for camping. A must have for emergencies.

Very bright and last a long time.

They are very bright and do last for at least 12 hours. After a few hours they are not as bright as when first activated and they get dimmer over time but they would still be very visible in the dark or low light conditions.

I bought these initially for halloween decorations, but it rained on halloween and messed up my plans. So, I ended up just randomly tossing these out in the yard for kids to pick up and carry with them as it got dark. They were a big hit and it was great seeing the kids faces 'light up' (pun intended) as they picked them up and walked off to the next house. Will definitely be doing this again next year.

These chemlights work. The green is the brightest, Red is second brightest, and the blue is the dimmest. The lights were activated at 6pm and at 11am the next day they where still giving off light. They started bright and after about 4 hours the reaction settled in and they lost some brightness, but were still usable. Visible at distance in complete dark out to about 25 feet with the naked eye, night vision they were visible out to about 100 yards. When first lit, they would light a 12x12 room. After the 4-hour mark, they would dimly light an 8x8 room. Did not have yellow or white in the package.

Perfect 👌🏻

Awesome stuff.like it!

These sticks provide ample amount of light for dark areas.
