look here for an AA zoom light, but 1 AA is few maybe btw a 14500.. I think that a single protected lion cell wont kill your child
or to be safe a 3 AAA zoom light like the C30
btw still if them look the focused led inside can hurt their eyes
or an uv led light to have the right frequency to make move the tecnobugs
you can buy them glasses.. btw dunno the temper and ages
...edc that play with his solar powered cockroaches would scare me more of his avatars xD
