Wiz is our Top Pick for kids. Easy to use. Not too bright, diffused light at about half the brightness of the Flood mode of the Spot. Fun color mode. Dimmable, and remembers last setting to avoid blasting siblings eyes. It is hard for kids to get the batteries out, presumably to kid-proof them for safety, which seems like a great idea to this Dad.
For parents, the Wiz is a safer light for use by younger kids, that is fun and easy to use.
