Some people never actually experience a need for boat lights. Some do. But those who do need underwater lights for a few very different reasons.
Reason 1: Night fishing. This is probably the reason most of my subscribers are looking for underwater lights. Indeed, an underwater light is invaluable when you’re fishing at night and need to attract fish. It is an old and reliable method.
Reason 2: A diver’s beacon. If you like diving, especially diving in the dead of night, underwater boat lights can be literally a lifesaver. You don’t want to miss your boat by a couple of hundred feet when you’re rising back to the surface, and to find it after you’ve hit the surface again is not very reliable, because your watercraft can be concealed by waves or even other boats. However, if you have underwater boat lights installed, that will no longer be a problem for you.
Top 5 Underwater Boat Lights in 2019
1Partsam Underwater Lights — Low Heat Profile
These underwater lights come in a pack of four. But that, of course, is not their main advantage. Their real strength is light intensity, power consumption, and a wide aperture. These boat lights meet all IP68 requirements and draw as little as 250 mA. The working voltage is from 10V to 30V. At the same time, the Partsam lights emit very low heat.
Installation is super easy, but you have to drill holes for screws and wires. The lights will endure any tests of time and weather.
If you want, you can install these lights above the waterline, but installing them below it is the real thing. The lights work great at attracting fish and highlight a boat’s wake like it’s made of liquid green fire.
- Wide aperture
- Light intensity
- IP68 protection
- Draws 250 mA
- Installation is super easy
- Low heat emission
- You have to drill holes for screws and wires
2Tidal Wake Drain Plug LED Light — Most Beautiful Lights
If drilling holes to install underwater lights is too much for you, I advise that you try this Tidal Wake LED light. Just as the name suggests, this light will add some glow to your tidal wake, but it’s not the only thing it can do.
The IP68-protected Tidal Wake light comes in 4 colors, and it is designed to replace the standard ½” drain plug. That limits your options as to where to install the light, of course, but on the upside, no mechanical work is needed.
It is not without drawbacks. Heat removal is a problem for this light. However, you won’t come into this problem face to face unless you install this light out of water. I strongly suggest that you don’t do that. If you want to test the light, limit its work out of the water to no more than 60 seconds. Otherwise, it’s going to overheat. The Tidal Wake light does come with overheating protection, but every time it’s triggered the life cycle of the light is decreased significantly.
On the bright side, the light is super bright and has a light intensity of 1800 lumen and a life cycle of 50k hours. That’s perfect for all sorts of activities, including fishing, swimming, and diving. On top of that, it also makes your boat look way greater.
I can’t promise super-low power consumption, but it does draw only 27W. Perhaps, you will find many cheaper lights, but they will offer you a lower light intensity in return for the low price.
- Designed to replace the standard ½” drain plug
- No mechanical work is needed
- Light intensity of 1800 Lumens
- Life cycle of 50k hours
- Limits your options as to where to install the light
- Heat removal is a problem for this light
3Lumitec SeaBlazeX Underwater Light — Best Overall
If 1800 lumen isn’t going to cut it, how about four thousand lumens? That’s what you get with this Lumitec underwater light.
Actually, Lumitec lights are some of the best, and that is also true for their underwater lights. Not just SeaBlazeX but also others. Still, why Lumitec?
Because they use naval grade bronze in their products and do quite aggressive tests on them. And yet, here is a light that endured all of them.
The light is available in 4 colors, all with strobe mode and crossfade mode. The light makes a terrific decoration for the bottom of your boat, but thanks to the sheer light intensity, it is one of the best lights for fishing on the market.
Unlike the Tidal Wake, the SeaBlazeX can operate above the waterline thanks to its low heat emission. Of course, that comes at a price.
- Four thousand Lumens
- Can operate above the waterline thanks to its low heat emission
4Y-knot Typhon Triple Head 3000 Lumen Blue Underwater LED transom Light — Most Intricate Design
How to light up the water under your boat in three directions simultaneously? You can use three lights. You can make a very complex system of semi-transparent mirrors (and that’s going to be such a pain in the neck to operate). Or, you can just get a triple-head light. The Y-knot Typhon is what you need exactly, as long as you don’t mind the color blue.
It’s not as powerful as some other lights, but it does flash 3000 lumens in three directions. Its primary purpose is to make your boat stand out, but it’s suitable for fishing and for divers.
- 3000 Lumens in three directions
- Suitable for fishing and for divers
- Not as powerful as some other lights
5Bright Night Fishing 15000 Lumens Light — Most Bright Lights
Want to get serious with your fishing? Here come a 15k Lumens light specially designed for fishers. The light comprises of 300 LEDs and lights everything up in a 35 feet zone. It going to draw all the fish to your boat, the only thing you still have to think about is how to get that big fish of yours out of the water.
I recommend that you hook it up to a single 12V battery. It’s going to last up to 43 hours. In ideal circumstances, you understand, but even with that caveat, it’s still going to be good for three to four nights on a single charge. Or, you can buy a 120V AC power adapter that is sold separately.
It is not a mountable light, unlike every other light on this list. No, it is made for fishing, and it is meant to be thrown overboard. Don’t worry, the light is self sinking, and its durable cord is suitable for 25 feet.
- A 15k Lumens light
- Lights everything up in a 35 feet zone
- Up to 43 hours
- Self sinking
- 300 LEDs
- Not a mountable light
