What did we upgrade in 2019?
We upgraded KINGWILL submersible led lights. Unique polygonal design is more solid than circular design. Thanks to the thickened sealing ring, its waterproof performance is increased by 50%.We upgraded the original remote control, the linear remote control distance increased from 10M(33FT) to 15M(50FT), no longer have to worry about not being able to control the underwater lights. It will give you a better experience than others.

Where can these lights be used?
Here are some great colorful LED waterproof lights that can add color and beauty to anything with water in it. From a small glass flower vase to a hot tub, to a fish tank or fountain, to a small pool, and waterfall or other water feature in your yard, you can drop in one or more of these waterproof lights and they will infuse the water with colored light. These lights can be used in non-water environments as well, of course. They'll make a nice nightlight or accent light anywhere in your house,and since they're fully waterproof, they can be used outdoors in any weather, too.

How to use these underwater lights?
The lights are powered by 3 AAA batteries (not included). To insert and replace batteries, just unscrew the bottom of the light. When twisting the light closed again,make sure the rubber O-ring is in place and that the bottom is closed snuggly to ensure the light stays dry inside.
Then you can use the included remote control to turn the light off and on,to choose from any of 16 different colors, to select a brightness level and to optionally activate one of four different dynamic color-changing modes.
