Jiawill 316L Underwater Stainless Steel Drain Plug Light

With a lighting upgrade, we can make our boat look as slick as a seal, and as attractive as an anglerfish. All we need is a decent LED light and a surface to mount it. With some of these babies, we do not even need to pre-drill.

One of the reasons we fancy these LED lights for our boat is they come with a rubber gasket. What this little rubber thing does is create a tight seal, leaving no room for water to sneak in and mess with our lights. Plus, they’ve got a stainless steel bezel. Besides adding to the light’s look, this feature helps to prevent any potential damage to the light’s insides, making it quite the catch for our underwater lighting system. Plus, if the lumen output and color underwater light options do not get you hooked, the ease of installation sure will.

  • Installation can be a bit of a hassle, especially if you are a rookie in the DIY department. Some lights might require professional installation, adding to the overall cost.

A Guide to Selecting the Most Suitable Underwater Boat Lights

Choosing the right underwater boat lights might not be as simple as picking the shiniest one. There’s a ton of factors to consider, and we’re here to guide you through them. Let’s dive in.

  • Considering Lumens and Beam Angle in Underwater Lighting

You can’t discuss underwater lighting systems without talking about lumens and beam angle. That’s the measurement of light brightness—more Lumens equals more brightness. But remember, brighter ain’t always better. What’s more important is the balance between brightness and coverage.

That’s where the beam angle comes in. A wider beam angle means more coverage, but less brightness. Same as lumens, finding the right balance is key. It means ensuring the light’s bright enough to spot a mermaid’s purse underwater, but wide enough to catch sight of Neptune’s kingdom.

  • Understanding the Importance of Light Housing Material

Housing material is also very important in a boat light. Think of it like a scuba diver’s wetsuit—it gotta keep things dry and take a beating. The material needs to withstand the harsh marine environment and resist corrosion. That’s why most high-quality housings are made from marine-grade plastics or bronze alloys. And while they might cost you a pretty penny, they sure do deliver in durability and looks.

For those of you sailing in the saltier seas, look for materials like treated metal that can resist rust. If you are not mindful, rust will claim your boat before Neptune does. So be sure to find a light with a tough-as-nails housing that can keep rust at bay.

  • Aesthetics vs Function: Color Options in Underwater Boat Lights

The clash of aesthetics and function is the age-old debate. When it comes to color options in underwater boat lights, both sides have their say. Those favoring aesthetics might opt for marine lights with vibrant colors, turning their voyage into a light show. Others, aiming for function, might stick with whites and blues as they penetrate water better.

But here’s the kicker: the housing matters here too. Marine lights with 316 marine-grade stainless steel housing not only look sleek but also outlast most others in durability.

  • Installation Process of Underwater Boat Lights

Underwater boat lights are not quite your run-of-the-mill Saturday morning project, but not exactly rocket science either. Now, some of these boat lights come with heavy-duty 316 marine-grade stainless steel housing – and let me tell you, that’s good stuff. It means these lights are tough, resilient, and built to withstand all the craziness the sea can throw at them.

When it comes to installing them, it’s a whole lot simpler if the lights come with the necessary hardware parts included. That means no extra trips to Home Depot or Lowe’s. You just fasten them to the transom, hook up the wires, and you are ready to live that beautiful, aquatic, LED-lit life. The temperature protection feature on some models even allows you to mount them above water. If you are going for outboard lighting, make sure to get at least three lights. Otherwise, you’ll be dealing with an annoying shadow effect that nobody really wants.

  • Balancing Performance and Budget

Let’s get down to the crux of the matter – performance and budget. There’s a mighty bunch of boat lights out on the market, and they’re all shouting for your attention with their flashy specs and shiny advertising. Some of them, like the Shadow-Caster SCR-24 surface-mount light, come with features that would leave your friends slack-jawed in amazement. Imagine, changing from a solid blood red to a pulsing rainbow with just a flick of a switch – from the dock, no less. 

These lights can turn your boat into a floating disco, but they come with a hefty price tag attached. On the other side of the spectrum, more affordable options may be easier on your wallet, but might lack the high-tech features or durability. Look for lights with solid safety features, like reverse polarity protection – it’ll save you from a potential electrical nightmare.

And ideally, you want lights that work equally well in saltwater and freshwater conditions. Just in case you feel like switching up your sailing venue. Lastly, always remember, professional installation can be a lifesaver when it comes to boat lights. Trust me, it’s worth every hard-earned cent to have it done right.
