There are several companies that make these little LED lights, and just about all of them are great. The red ones are handy for climbing in and out of deer stands without spooking critters. You can attach them to fanny pack zippers and key chains, so they are always handy.

We use them for charging up luminescent jig heads for walleye and crappie ice fishing. They do a great job on the luminescent corkies also. The blue one does the best job on chraging the phosphorescent paints used on jigs and corkies. Hope this helps you ou.
