10 Best Underwater Boat Lights 2025 in the United States

The Lumitec SeaBlaze Mini Underwater LED Boat Lights are designed specifically for smaller boats like dinghies and skiffs, offering a bright output of 700 lumens. This level of brightness is excellent for creating ambiance or aiding in fishing activities, making them a practical choice for boaters looking to enhance their nighttime experience on the water. One of the standout features is the durable marine-grade anodized aluminum housing, which ensures these lights can withstand tough marine environments, providing longevity and reliability.

Installation is quite user-friendly with versatile mounting options; you can easily transom mount them above or below the waterline, which is a great advantage for different types of boats. They are compatible with a wide range of 12-volt to 24-volt power systems, adding to their versatility in terms of electrical setups.

The lights are ideal for smaller boats, but the 700 lumens may not be sufficient for larger vessels that require higher brightness. Users looking for a strong, expansive light might find these lacking in performance. Additionally, the compact design might limit the light spread, which could be a drawback if you're planning to illuminate a larger area. Lastly, while they come as a pair, some may find the price point a bit high compared to other options in the market, especially if they are on a tight budget.

The Tendelux Underwater Fishing Light is a versatile and efficient solution for enhancing night-time fishing endeavors. It offers 2300 lumens of bright green LED light, consuming only 23 watts, which balances brightness and power efficiency. This light is designed to attract phytoplankton, baitfish, and predatory fish, making it easier to catch fish in both fresh and saltwater environments. With an IP68 rating, it ensures durability under water. The light is made from resin and plastic, which contributes to its lightweight design.

It comes with a 30ft power cord, 110V AC power adapter, and newly added 12V DC battery clamps and a cigarette lighter adapter, providing flexibility in power sources. The product also includes a waterproof carrying bag, user manual, and an 18-month warranty, making it well-supported by Tendelux. However, users should be aware of the need for regular maintenance to prevent marine fouling organisms, especially if used in seawater for extended periods.

This light can be a good fit for dock, boat, or kayak fishing enthusiasts looking for a reliable and efficient way to attract fish at night.

The Lumitec Lighting 101460 is a strong contender in the underwater-boat-lights category. With a brightness of over 2000 lumens in white, it provides ample lighting for night-time boating or fishing. It offers a full-color spectrum (RGBW), allowing for a variety of lighting colors without the need for external controllers, which is a significant convenience for users. The light is surface mountable, which means it can be installed without the need to drill holes in your boat's hull - a big plus for easy installation and maintaining the integrity of your boat.

Additionally, the light self-isolates from any metallic surfaces with a simple 2-wire hookup, reducing the risk of corrosion or electrical issues. The housing is made of naval grade bronze with heat tempered glass, ensuring durability and longevity even in harsh marine environments. Its power consumption is 25 watts, which may be a consideration if power conservation is a priority on your boat. Being waterproof adds to its suitability for underwater use, but its size (18 x 10 x 6 inches) and weight (1.55 pounds) might require you to ensure you have adequate space and mounting support on your boat.

Available since 2017, it may not feature the latest technology but still remains a reliable choice.
