Buying Guide: Why do I need underwater boat lights?

If you want to drive your boat at night then installing some underwater boat lights is essential. These amazing lights sit underneath your boat and serve to light up the water around you. When cruising on the water there are always dangers that you need to be aware of, and increasing your visibility whether on misty day or at night is one way of reducing your risk of an accident.
In addition to safety, the experience of sailing at night with your lights switched on can be an inspiring experience. Seeing the waters lit up around you (in vivid colors if you’ve opted for colored lights) with the stars above you is truly uplifting. Not to mention if you’re going to be night fishing your underwater boat lights will point you in the right direction.

What are the different types of underwater boat lights?

There are two different types of underwater boat lights, these are incandescent lights and LED lights.

#1 Incandescent lights

Incandescent lights are the cheaper of the two types of underwater boat lights. However, this type of light bulb uses around 5 times as much energy to create the same amount of light as LED bulbs. The higher the wattage the brighter the light, with the light being produced by heated filaments. The pros of this type of light are that they give a warm glow and are pretty cheap. However, the cons outweigh the pros when it comes to choosing incandescent bulbs for your underwater boat lights. These bulbs do not last long, use an excessive amount of energy and are actually not very happy in the water.

#2 LED Lights

LED lights, on the other hand, are much more suitable as an underwater boat light. They are much more energy-efficient than an incandescent light and do not produce a lot of heat by comparison. Another benefit of LED lights is that they last for 100,000 working hours compared to incandescent lights which last for just 1000. While they are more expensive than incandescent lights, their energy efficiency, durability, strength, and ability to withstand immersion in water make them well worth the money.

What to look out for when buying underwater boat lights

#1 Brightness of the Bulb

The brightness of your boat lights will depend on the number of lumens they have. Lumens are the measure of the amount of light that can be seen by the human eye, so the higher the lumens the brighter the light will be. Aim to go as bright as your budget allows to ensure you get the maximum visibility when you use your boat at night.

#2 Color of the lights

While for many a single color boat light will suffice, some prefer a little more exciting option. Look out for LED boat lights that offer more than one color so that you can light up the water with a rainbow of colors. You can also get led lights that have strobe and crossfade abilities if you require it. It is also important to consider the width of the beam of your underwater boat light of choice.

#3 Ease of installation

When it comes to underwater boat lights, they do vary in their ease of installation. It’s a good idea to look out for underwater boat lights that are flexible with where they can be mounted whether it be the transom or the trim tab.
Most underwater boat lights are installed by drilling holes into your boat and then bolting them in. However, some come with an airtight mounting clamp which doesn’t require any drilling or bolting. Make sure you always check the manufacturer’s instructions before installing and it is wise to get the help of an expert if you’re unsure. The last thing you want is to damage your boat or your brand new underwater boat lights.

#4 Protection

As your underwater boat lights are going to be in contact with water they need to have a strong protective housing that protects them from the elements. There are a variety of materials used to house underwater boat lights including aluminum bronze, translucent polymer, and marine-grade stainless steel. While all three materials are robust and durable if you’re going to have your underwater boat lights permanently submerged underwater then go for the saltwater resistant aluminum bronze.
