I don't have either of them but I've gotten a lot of other Brunton products and never had a problem with them. I don't know how powerful a light those two offer. They are neat little toys, though, especially the light/lighter!
Your kids might be better off with something like the Inova X5T with lithium batteries that can sit a long time until they're needed and the 5 LEDs give a good area light for about 20 hours, I think they're rated.
