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 Daryle Grove

this little pool light works great in my pool. the remote control has a bright and dim button and lots of patterns and colors to choose from. it comes with a magnet to stick it on the inside of your metal walled pool - but since we added a foam insulation padding to our pool wall before putting up the liner, it would not stick. So we are using the 3 suction cups that attach to the back of the light. it sticks on to the liner and won't slide down. my pool is only 15 ft. across, so it adds light all the way across. if you have a large pool, it probably wouldn't give off as much light.
