10 LED RGB Submersible IP67 Waterproof Outdoor Swimming Pool Light Battery Operated.
Interesting device that can be submersible on the pool or other water tanks. I use it in a “dry” project where I need to control the color of lights. The three internal “AAA” batteries go inside the device and it is completely secure to use on water. The light is strong and the colors can be chosen through an included remote control. Very nice.
