6 Best Underwater Boat Lights: Reviews and Buying Guide for 2020

The best underwater boat lights can make your boat more visible, enhance its appearance, and make your dive sites safer. Adding lights to your boat is easy since manufacturers offer simple mounting systems for these products and make waterproof housings for LED lights.

Here is what you need to know about selecting underwater lights, and a few products we recommend.

What to Look For in Underwater Boat Lights

The waterproof rating is one of the first things you should look at when selecting an underwater boat light. The IP68 rating indicates that you can use a light underwater without damaging it. A product that doesn’t have this rating might not have a durable housing or might not last long in the water.

If you need lights that you will use in saltwater, look for lights with housing that uses a protective coating or another feature to prevent corrosion. Marine-grade materials are an investment that will last longer in saltwater.

LED lights make the best underwater boat lights because they’re bright, durable, and energy-efficient. We recommend choosing white or blue lights for visibility, but you can find a wide range of colors that you can use for aesthetic purposes.

The brightness of an LED light is measured in lumens. You can find basic underwater lights in the 500 to 1,000 lumens range, or invest in a 2,000 to 3,000 lumens light if you want better visibility from further away.

Lastly, you should pay attention to the hardware and mounting system that comes with your new underwater light. It should be easy to mount on your boat’s hull.

Types of Underwater Boat Lights

You will come across different light shapes and mounting systems when shopping for underwater lights. Make sure you choose a light adapted to your needs:

  • Floodlights or navigation lights are larger LED lights with more reach. They help you see further at night and can illuminate a dive site.
  • Fishing lights are lights that you can set in water to attract fish or observe wildlife.
  • Spotlights are lightweight LED lights designed to be handheld. It’s best to keep a spotlight on board for safety purposes.
  • Underwater aesthetic lights allow you to improve the appearance of your boat. These lights can enhance visibility to some extent, but their main purpose is to create an aesthetic effect. These lights often change colors.
  • Drain plug lights and other smaller LED lights are designed to illuminate a specific fixture and make it more accessible.

Note that you can build a customized light system by combining different types of lights and thinking about light placement on your boat.
