How To Select Marine Underwater Lights

Lighting that can illuminate under the water are perfect for outrigger spreaders and can be placed under the hull or on the transom. Whether you're a fisher, angler or just like to boat at night, marine underwater lights can be perfect for you. They've been around for years, but now they're more technologically advanced. Of course, they're waterproof, but they can be aimed at different areas, such as straight down, and can be more reliable. While they're perfect to see and to attract fish, they're also cool and can impress guests.


Newer marine underwater lights use LEDs (Light-Emitting Diodes) that can use less energy, work at lower temperatures, handle vibrations and last longer. Plus, they don't contain mercury and aren't an environmental hazard like fluorescents, though they can cost slightly more.

Options For Mounting

These lighting options are so versatile that they can be mounted in multiple ways. Surface-mount light is perfect for sailboats and smaller powerboats. They can be placed on the side of the hull or mounted on the transom.

Trim tab lighting is attached the stern of small powerboats and drain plug light options screw into the drain plug of your powerboat.

Thru-hulls and interchangeable thru-hull light can be used on bigger powerboats and are larger in diameter. Interchangeable options allow you to change them from inside the boat, but thru-hulls can also have lighting replaced on land.


The brightness of the LED lighting will determine how far the light will travel when it is under the water. If you're hoping to attract fish, you may need more Lumens, but if you're just hoping to create some ambiance, it may not matter how bright they are.


The width of the beam should also be considered when choosing marine underwater lights . In most cases, you can choose from narrow spot and wide flood lighting. Narrow-spot lighting uses smaller angle degrees. Therefore, if you want to use one or two lights and illuminate past the boat, wide-flood lighting may be more appropriate.


The light can also come in different colors or even multicolor options. The actual light can be different colors, as well, to match your d├ęcor. Most people find that blue works best in almost all water conditions. If you're going into silt-laden waters, green may work best while white works better on sandy, shallow bottoms. Likewise, red can make any water come alive and look fantastic.
