The Goldlife B5 Underwater Boat Lights are designed for boat owners looking for strong and reliable underwater lighting. With a powerful brightness of 2x3000 lumens, these lights offer excellent illumination, making them very effective for enhancing visibility around your boat, especially at night or in murky water. The blue color adds an attractive glow often preferred for aesthetic and fishing purposes. The lights feature a sturdy 316L stainless steel shell and a clear polycarbonate lens, which makes them corrosion-resistant and durable in harsh marine environments. Their slim, ultra-thin design allows them to blend seamlessly with your boat’s exterior without being bulky.

These lights are fully waterproof with an IP68 rating, meaning they can be submerged without risk of water damage. They are filled with marine glue to prevent leaks and are built to last up to 80,000 hours, which is a long service life for underwater lighting. Installation is generally straightforward since they use a 2-core wire and can be mounted both underwater and above water. However, installation might be more expensive or complicated than some other models, which could be a consideration if you want a quick DIY setup.

The power source is DC 10-30V, compatible with most boat electrical systems and RVs, providing versatility. These lights are priced higher than some competitors, which may deter budget-conscious buyers. The three-year return policy offers confidence in quality. If you want premium, bright, and durable underwater lights for your yacht, pontoon, or fishing boat and don't mind investing a bit more upfront, the Goldlife B5 is a strong choice that delivers excellent performance and marine-grade protection.

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.

The waterproof quick-connect plug and storage bag simplify removal and storage, adding convenience when trailering. The 160-degree beam angle provides a broad flood of light, enhancing safety and visibility while cruising, swimming, or fishing at night. Additionally, it features a built-in driver with overheat protection and comes with a 3-year warranty and a 50,000-hour life span.

Its specialized design means it may not be compatible with all boat models. Moreover, while blue is aesthetically pleasing, it might not be the preferred color for all users.
