Lumitec SeaBlazeX2 LED Underwater Light - White/Blue
Lumitec SeaBlazeX2 LED Underwater Light - White/Blue — Product description
The Lumitec SeaBlazeX2 Dual-Color Underwater LED Light (MPN 101516, UPC 089300015167) is Lumitec's evolution of the industry-standard SeaBlazeX - same compact bronze surface-mount housing, same simple 1/2-inch through-hull installation, but with 60% more light output and selectable dual-color operation. 5,000 lumens from 28 LEDs in a 3.94-inch diameter housing only 0.85 inches deep. Switch between full white (general transom illumination, dock approach, water clarity), full blue (the classic fishing-attractor and aesthetic glow), internally synchronized white/blue cross-fade, and strobe modes - all from the same 3-wire hook-up with no external controller box required. Marine-grade bronze body and heat-transfer faceplate keep the LEDs cool underwater for full-life output. IP68 sealed - completely waterproof for permanent submerged installation. 10-30 VDC input (works on both 12V and 24V boats). Backed by Lumitec's 3-year limited warranty. Engineered and assembled in the USA.
The Lumitec SeaBlazeX2 is the dual-color successor to the SeaBlazeX - the underwater light that defined the surface-mount underwater LED category for recreational boats. The X2 keeps everything that made the X a category-defining product (compact size, easy install, sealed bronze housing, no external controller) and adds two upgrades the market asked for: 60% more light output and selectable dual-color operation with cross-fade and strobe.
What the 60% output bump actually delivers. 5,000 lumens out of a single SeaBlazeX2 is enough to fully illuminate the water behind a 25 to 35-foot transom in clear or moderately turbid water. Two SeaBlazeX2 units (one each side of the transom) light up the entire stern area for dock approaches, swim platform safety at night, attracting baitfish and gamefish, or just creating the underwater glow that's become a defining aesthetic for modern boats. The output increase over the original SeaBlazeX is meaningful - if you already know the SeaBlazeX, the X2 is noticeably brighter side by side.
Selectable dual-color modes. The SeaBlazeX2 isn't just white-or-blue, it's a multi-mode controllable underwater light with no external controller box: (1) Full white output - for general transom and stern lighting, dock approaches, water clarity assessment, and night swimming visibility. (2) Full blue output - the classic underwater light color for fishing (attracts baitfish, which attract gamefish) and the aesthetic underwater glow that reads as "yacht" at dock. (3) Internally synchronized white/blue cross-fade - the X2 smoothly transitions between colors on a built-in timing loop. (4) Strobe mode for attention-getting effects. All four modes are selected by the install wiring - simple 3-wire hook-up with no separate controller required.
Why no external controller box matters. Most competing dual-color underwater lights require an external controller box mounted in a dry locker, which adds install complexity (extra wiring run, mounting hardware, troubleshooting failure point) and cost. The SeaBlazeX2 puts all the color control electronics inside the underwater housing - your install is just the same 3-wire run as a single-color light. Fewer parts, simpler wiring, fewer failure points, lower install cost. This is a meaningful win for boaters doing self-install or for refit yards quoting underwater lighting packages.
The compact form factor that made the SeaBlaze category. 3.94-inch diameter, 0.85-inch profile - that's it. The SeaBlazeX2 fits where bigger underwater lights can't. Installation cuts a 1/2-inch (half-inch) through-hull hole for the wiring tail - that's all the hull penetration required. The light itself surface-mounts to the transom or hull using the included sealing gasket and four stainless screws. Total install time on a clean transom: under 2 hours for a single light, including running the wire. Surface mount also means no in-hull intrusion - the entire light is outboard of the hull skin so you preserve interior space in the bilge or stern locker.
Marine-grade bronze housing and heat-transfer faceplate. The bronze body acts as the heat sink for the LEDs - waste heat from the 60W LED array transfers through the housing to the surrounding water, which is an essentially infinite heat sink. Bronze is the right material here because it's strong, doesn't electrolytically react badly with stainless fasteners, and resists marine corrosion over decades. The bronze finish is a deliberate aesthetic choice that reads as quality on premium transoms (especially against gel-coat white or dark blue hulls). The face that contacts water is engineered specifically for thermal transfer - the LEDs run cool, the lumen output stays at spec for the rated life, and the failure mode isn't gradual dimming from heat damage like cheap underwater lights.
IP68 sealed for permanent submerged installation. IP68 is the highest dust and water ingress rating - certified for continuous immersion at depth. The SeaBlazeX2 housing is completely water-sealed, meaning the unit stays underwater 24/7/365 for years without internal moisture damage. There's no maintenance access required because there's no maintenance to do - the unit is fully sealed for life.
10-30 VDC input range. Works on both 12V boats (the recreational standard) and 24V boats (sportfish boats, larger yachts, some commercial vessels) without modification. The same SeaBlazeX2 unit on the shelf works for both system voltages - no part number split, no risk of buying the wrong voltage version. Input voltage protection is built in, so brief voltage spikes from engine cranking or alternator surges don't damage the LEDs.
Simple 3-wire installation. Power positive, power negative, and a third wire that selects the color mode. Run the wire through the 1/2-inch through-hull, seal with the included grommet and marine sealant, route to a switch panel or color controller at the helm, done. The wire isn't tiny gauge - it's appropriately sized for the 60W load over typical runs. Lumitec includes the install gasket and basic hardware. You don't need to source obscure parts or pay for an upcharged install kit.
3-year Lumitec limited warranty. Lumitec is one of the more straightforward marine warranty processors in the industry - if a SeaBlazeX2 fails within 3 years, the warranty claim is reasonably fast and they don't fight obvious failures. Engineered and assembled at Lumitec's USA facility, which matters for parts availability and warranty turnaround. Field reliability on the SeaBlaze series is among the best in recreational underwater lighting.

Frequently asked questions
How many SeaBlazeX2 lights do I need for my boat?
General rule for recreational use: one pair (port and starboard) for boats up to 30 feet, two pairs for boats 30 to 45 feet, three or more for boats over 45 feet. The 5,000-lumen output per unit is high enough that you don't need to over-buy - a properly placed pair on the transom of a 30-foot center console or cruiser will fully light up the stern. For high-end yachts looking for the full underwater glow effect along the hull length, more units spaced down the sides at the chine line produce the magazine-cover look.
What is the install hole size?
1/2 inch (half-inch) through-hull hole. That's all the hull penetration required - just enough to pass the wiring tail through to the inside of the boat. The light itself mounts on the surface of the transom or hull using the included gasket and four stainless screws. No big cutout, no hull-thickness specification to worry about (surface mount works on any reasonable hull thickness).
Does it work on a 24-volt boat?
Yes. The SeaBlazeX2 has a 10-30 VDC input range, so the same unit works on both 12V (the recreational standard) and 24V boats (sportfish boats, larger yachts, some commercial vessels) without modification. Built-in voltage spike protection handles brief surges from engine cranking or alternator transients.
How do I switch between white, blue, cross-fade, and strobe?
The SeaBlazeX2 uses a 3-wire install where the third wire is the color-select signal. The simplest setup uses a multi-position switch at the helm: position 1 = white, position 2 = blue, position 3 = cross-fade, position 4 = strobe. Lumitec also offers compatible color controllers if you want centralized control of multiple lights. Either way - no external controller box mounted in a locker, because all the color electronics are inside the light itself.
Will it work on aluminum hulls?
Yes - the bronze housing and proper electrical isolation in the install (use the included gasket, follow the install instructions for sealing) prevent galvanic interaction with aluminum hulls. The light itself doesn't contribute to galvanic issues. Many aluminum-hulled sportfish and workboats run SeaBlazeX2 lights without problems. For maximum protection on aluminum, install Lumitec's recommended isolation hardware and follow standard underwater fitting best practices.
Can I install it myself?
Yes - this is one of the simpler underwater light installs in the category because of the surface-mount design and small through-hull hole. Steps: (1) pick mounting location on transom or hull (clean, flat surface below the waterline), (2) drill the 1/2-inch through-hull hole and four screw pilot holes, (3) feed the wire tail through, seal with the included gasket and marine sealant, (4) attach the light with the four stainless screws, (5) run the 3 wires to your switch panel inside the boat. Realistic time: 2 to 3 hours for a single light if you've installed marine accessories before.
How hot does it get?
Cool underwater, hot in air. The bronze housing transfers waste heat from the LEDs to the surrounding water - in operation underwater the housing stays at near-water-temperature. IMPORTANT: do NOT run the light out of the water for more than a few seconds for testing. Without water cooling, the housing temperature rises rapidly and can damage the LEDs. Quick bench testing (30 seconds to verify the unit powers up) is fine, extended dry operation will damage it.
Why blue light specifically for fishing?
Two reasons. (1) Blue light penetrates water further than other colors before being absorbed - so blue extends the visible-light range underwater. (2) Plankton and baitfish are attracted to blue light, and gamefish are attracted to baitfish concentrations. Setting a SeaBlazeX2 to blue mode for nighttime fishing at anchor pulls in a baitball that pulls in the predator fish you actually want to catch.
What's the difference vs the original SeaBlazeX?
Two main differences: (1) 60% higher light output - the X2 is significantly brighter than the X side-by-side. (2) The X2 is dual-color (white plus blue with cross-fade and strobe) where the original SeaBlazeX comes in single-color variants. Same form factor (3.94-inch diameter, 0.85-inch profile), same bronze surface-mount housing, same simple installation - the X2 is a drop-in upgrade in the same physical footprint with more output and more modes.
Is the cross-fade timing adjustable?
No - cross-fade timing is internally synchronized at a fixed cycle designed to look natural and elegant rather than fast and distracting. The fixed timing means multiple SeaBlazeX2 lights all stay synchronized with each other (when wired off the same switch they fade together). If you want fully programmable color effects, Lumitec's SeaBlaze TX or higher-end models offer that programmability.
What is the warranty and what is covered?
3-year Lumitec limited warranty covers manufacturing defects in materials and workmanship. Lumitec is one of the more straightforward warranty processors in marine - failures get handled without a big fight. Engineered and assembled in the USA at Lumitec's facility, which keeps warranty turnaround reasonable. Field reliability on the SeaBlaze series is among the best in recreational underwater lighting - real-world failure rates are low.
Will it fit on my dive platform or swim platform?
Yes if the platform has a flat surface below the waterline and you can route the wire through to the boat interior. The 3.94-inch diameter footprint fits on most platforms. Some swim platforms have a flat underside that's perfect for surface mounting these lights pointing down or aft for swimmer safety and aesthetic lighting at anchor.
