Seeing those hanging lights brings to mind a couple of Luci Lights I bought last year. They are solar charged, no batteries ever. They are inflatable for packing down into a flat circle. They have a multitude of colors one can choose and a charge lasts many hours. The brightest color setting could 'almost' serve as a rewarding light.
I recently saw a solar charged light array with some hanging lighted balls that also have a variety of colors and can be set to alternate between various colors. These are on the website Wish.com. I might be picking up a few of these for my next whale magic adventure.
Thanks to all here, AND, bless our veterans tomorrow when you have the chance to show appreciation.
