Can't say I see the reasoning behind giving a child a key chain light. I've seen six-year-olds do just fine with a 2D Maglite.
Ha! great point. I just happen to have extra photon lights and he liked playing with them and was familiar. I mean C'mon, you don't have about four laying about? Completely unrelated but quite aptly, I bought him a mini GI angle head flashlight for his pack yesterday. He loves using mine around the house but its much to big for him.
