Lumitec SeaBlaze X3 Dual Color White/Blue Underwater LED Light

The Lumitec SeaBlaze X3 Dual Color gives you the two underwater colors most boaters actually use, white and blue, in one tough surface-mount fixture. This is the practical, value-minded member of the SeaBlaze X3 family. If you don't need a full rainbow of color and just want a bright, reliable light that does blue for the look and white for the work, this is the one to reach for. And with a 5-year warranty behind it, it's built to be a long-term part of your boat.

It's a surface-mount light, which means it bolts to the transom below the waterline and only needs a small hole for the wire. You're not cutting a large opening through the hull the way you would with a thru-hull fixture, so the install is simpler and a lot less stressful, whether you're doing it yourself or having a yard handle it. Once it's on, it sits flush and clean against the transom.

Output is identical to the rest of the X3 line at 8,000 lumens, which is a genuine wall of light. Run the deep blue for that classic glow at anchor or drifting on a calm night, and the water lights up around the boat. Switch to white when you need to see, whether you're cleaning fish on the swim platform, checking the water before a swim, or drawing bait to the transom. The two colors cover the vast majority of real-world underwater lighting needs, and you flip between them without any app or controller required.

The X3 is the first Lumitec light to feature their DryLock technology, and it's the reason this fixture should outlast cheaper lights. DryLock brings together advanced thermal management, leak protection, and moisture prevention in one integrated sealing system, engineered specifically to keep water out and heat moving in the harsh, unforgiving world below the waterline. The light carries an IP68 rating and is CE certified, and the whole X3 platform was designed to raise the durability bar for surface-mount underwater lighting. That focus on sealing is exactly why it earns a 5-year warranty.

The housing is bronze, and that's not a small detail. A surface-mount light lives its entire life submerged in saltwater, and bronze resists corrosion and galvanic attack far better than plastic or lighter alloys. Combined with the compact shape, 3.94 inches in diameter and a shallow 0.85-inch depth, you get a fixture that stays put, stays sealed, and doesn't hang down into the water where it could catch a line or take a knock. The mounting hole is just half an inch.

Electrically it's easy to live with. The X3 accepts a wide 10 to 30-volt DC input, so it drops onto 12 or 24-volt boats without any special wiring. Draw is 5.5 amps at 12 volts or 2.5 amps at 24 volts, with related power around 65 watts. The white channel runs at 6500K with a CRI of 70 or better, so whites come through bright and true rather than dull. The light is PLI enabled and supports Timed Toggled Protocol for switching colors from a standard switch, and it's compatible with the Lumitec Poco system if you ever want to tie your boat's lighting into one control setup.

This is the smart pick for anglers and cruisers who want serious brightness and the two most useful colors without paying for full-color electronics they won't use. You get 8,000 lumens, a rugged bronze body, DryLock sealing, and a 5-year warranty, all in a surface-mount light that's straightforward to install and simple to run. It's honest, capable gear that lights the water beautifully and holds up to the saltwater it's built for. Pair a set on the transom and you'll have a boat that turns heads at the sandbar and earns its keep on every night trip.
