These AAA LED Underwater Lights are made to surface mount underwater and are water cooled for maximum efficiency. Underwater lights can be a big help when navigating through cloudy waters as they deflect the grainy particles and make the water look a whole lot clearer! They are made from non-corrosive and chemical resistant polymer which completely encloses the 10 LEDs and gives it a totally waterproof rating of IP68. The LEDs have a 50,000 hour life and give off 235 lumens of blue coloured light. This light is suitable for both 12V and 24V systems and comes with everything you need to mount it. Dont look past these underwater lights as an extra accessory for your boat!
