Bought these for camping with Girl Scouts, and they were a big hit. They were much too bright for nightlights, which is what I had originally intended them to be used for, but the girls loved them to hang up under the bunks to see better to play cards and stuff when it was raining outside. Several of the girls asked to take theirs home, so I let them.
I bought this 2-pack AND a 4-pack, so 6 total. Each light requires 3 AAA batteries. They are very bright, and they also have a strobe light mode.
