MegaWatt Underwater Dock Lights


The MegaWatt is a floating LED underwater dock light that puts out an amazing 22,000 lumens of light.

The light is held in place by a 3 lb weight attached to the power cord allowing you to adjust how deep the light in the water. Place the light higher in the water column for a larger circle of light or deeper to protect the light from boat traffic.

This is a Plug and Play system. You simply set the light to the depth you want, throw the light and weight into the water where you want them, and plug it in. It’s that simple!
