Lumishore SUPRA TIX404 Thru-Hull Underwater LED Light

There's a certain magic to lighting up the water around your boat after dark, watching baitfish gather and the wake glow behind you. The Lumishore SUPRA TIX404 is built to deliver that experience at full power. It's a dual-color underwater LED light, running blue and white, that produces a bright, wide wash of light through an ultra-wide 110-degree beam angle. Whether you're setting a mood at the dock, drawing life to the transom while you fish, or simply making the swim platform safer at night, this is a light that does the job with real output behind it.

The numbers tell the story. The TIX404 generates 18,340 LED lumens and a verified 8,150 fixture lumens in white, which is a serious amount of usable light in the water. It gets there with a purpose-built LED array. Twelve 10-watt emitters handle the white channel, while twenty-four 3-watt emitters produce the blue, all driven through a high-intensity chip-on-board array. That mix of dedicated white and blue LEDs is what lets the light produce clean, saturated color rather than a muddy blend, and it's why the SUPRA series has the reputation it does for punchy underwater light.

What really sets the TIX line apart is right there in the name. TIX means interchangeable, and this light is engineered so the internal LED array and its integrated driver live inside the hull. That's a meaningful design choice for anyone who's ever dreaded servicing gear below the waterline. Instead of hauling the boat or diving on the hull to work on the light, you can service the TIX404 from inside, which simplifies both the original installation and any future maintenance. The interchangeable design also means you have flexibility down the road if your needs change. It's the kind of thoughtful engineering that pays off over years of ownership.

Control is where the SUPRA system shines. The TIX404 is run by the SUPRA i-Connect Hub and Switch, or you can drive it directly from a compatible multifunction display or the optional Lumishore Display when you add the SUPRA Bridge Module. However you control it, you get a full palette of effects. You can switch between blue and white, fade smoothly between colors, adjust brightness to match the moment, and trigger a strobe in two speeds. Because the system keeps multiple lights synchronized, a whole array of TIX404 lights along the hull will fade, strobe, and change color together as one coordinated show rather than a scattered mismatch.

Underwater lights live in one of the harshest spots on any boat, so build quality is everything. The SUPRA TIX404 uses a marine-grade aluminum bronze housing, a material chosen for its strength and its resistance to the corrosion and marine growth that attack anything mounted below the waterline. The LEDs are rated for a typical life of more than 50,000 hours, so you're looking at many seasons of use before you'd ever think about the emitters wearing out. Lumishore backs the light with a 3-year warranty, which reflects the confidence they have in the construction.

On the electrical side, the TIX404 runs on 12 or 24-volt DC systems, so it fits the vast majority of boats without special wiring. Maximum current draw is 6.4 amps at 12 volts or 3.2 amps at 24 volts, figures that are reasonable for a light putting out this much output. The multi-channel internal driver manages the white and blue channels and delivers the smooth dimming and color control the SUPRA system is known for.

Mounting is flexible too. The TIX404 is suitable for transom, side, and bottom mounting, so you can place it where it makes the most sense for your hull and the effect you're after. Anglers often favor a transom-heavy layout to concentrate light where they're fishing, while cruisers might spread lights along the sides and bottom for an even glow all around the boat. Whichever way you go, the wide 110-degree beam spreads light generously so you get coverage without needing an excessive number of fixtures.

If you've been running dim, aging underwater lights, or you're outfitting a boat for the first time, the SUPRA TIX404 is a strong choice. It combines real brightness, rich blue and white color, smart synchronized control, and a hull-serviceable design that makes living with the light far easier over time. Add one to the transom or build out a full synchronized array. Either way, you're going to enjoy the water in a whole new light.
