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

Very bright and last a long time.

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.

Excellent. Bright and last a long time. The included plastic cord is not good - will not stay tied and breaks easily.

Long lasting. These are great for kids. Great nightlight or just a fun thing to have around

Lasted for 12 hours and is a good level of brightness

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.
