Review on 🏊 SHYMERY Waterproof Submersible LED Lights - White Pool & Pond Tea Lights (12 Pack) - Battery Sub LED Lights for Underwater, Fishing, and Celebration - Flameless LED Tea Light by Dave Cavazos

I used them after Hurricane Ida. I made little water lanterns out of them (water refracts light and glows brighter than tea lights) around the house so we can see in the middle of the night and not bump into things during the week when we haven't had electricity. Each tea light had about 24 hours of continuous use. You have exceeded my expectations. It will be interesting to use them for decorative purposes next time because I know they will last and provide good ambient lighting!
