I found beachballs.com and they have various size balls that have lights in them ...you can float in pond, hang from trees...cheap and durable. have a small pocket in the bottom for the light. Mine came with a small light ,battery operated of course, had white lights and changing colors too. I even got on that looks like the moon and also lights up. They will be way cool floating in my ponds. Cheap and easy breezy. when light dies I'll replace from the dollar store Yah.
