Review on KIWIHOME Submersible LED Pool Lights, Pond Lights With Remote, 16 Colors Underwater Lights, IP68 Waterproof Magnetic Bathtub Light Hot Tub Light With Suction Cups For Fountain Swimming Pool Aquariums by Doug Bunkers

Worked well submerged in my fountain for the first day, although the suction did not keep down, the provided metal weight did the job. The next day it would only stay on for about 30 seconds and then turn off. Has been that way ever since. I’ve changed the batteries, dried it out for a day, moved it outside the water, all with the same, 30 second result. Would not recommend.
