The Lumitec SeaBlaze X3 is a surface-mount underwater LED light that produces 8,000 lumens at power draw comparable to the SeaBlaze X2 it replaces. Released by Lumitec in early 2026, it has become the default underwater lighting upgrade for yachts running out of West Palm Beach. The reasons are practical, not cosmetic.
Brighter output. A drop-in mounting pattern that matches the X2 hole-for-hole. IP68 sealing under Lumitec's DryLock construction. A 5-year warranty. And, for the first time on a SeaBlaze fixture, music sync through the Poco controller system.
This guide walks through what the X3 actually does, how it compares to the X2 it replaces and the competitor lights yacht owners cross-shop, and why DRSA stocks it as a flagship Lumitec product. We've been supplying marine lighting since 1988, and the X3 is the underwater fixture we recommend most often for yachts running South Florida waters.
What Is the Lumitec SeaBlaze X3?
The Lumitec SeaBlaze X3 is the third-generation flagship in Lumitec's SeaBlaze surface-mount underwater LED series. It produces 8,000 lumens, runs on 10-30V DC, uses a solid naval bronze housing with no external driver, and is rated IP68.
It replaces the SeaBlaze X2, which Lumitec discontinued when the X3 launched. The X3 was engineered to be a direct upgrade: same mounting hole pattern, same wiring approach, same housing depth, with brighter output and updated smart features.
Two versions are available: Spectrum RGBW (full-color, programmable) and Dual Color White/Blue. Both ship from DRSA with free Economy shipping in the U.S.
Why Yacht Owners in West Palm Beach Pick the SeaBlaze X3
West Palm Beach is one of the most concentrated yacht markets in the country. Rybovich, Riviera Beach Marina, Palm Harbor Marina, and Sailfish Marina all sit inside a 10-mile stretch. Yachts here run salt water year-round, sit in slips through hurricane season, and are evaluated by their owners, captains, and crews on how they look at night.
Three things drive the X3's adoption rate in this market.
Output That Holds Up Against South Florida Water Clarity
Local water can be tannin-stained inshore and brilliantly clear off the inlet. The X3's 8,000-lumen output cuts through both. The wide beam spread produces a continuous halo around the hull rather than the spotty pools you get from underpowered fixtures.
Consistent Power Draw Across a Multi-Light Install
On a 60+ ft yacht with 6 to 10 underwater lights, amp draw matters. The X3 draws power comparable to the X2 it replaces, so refit shops can plan circuits using familiar load calculations without re-engineering the electrical setup.
Drop-In Upgrades from the X2
Most West Palm Beach yachts that already have underwater lights are running X2s. The X3's identical hole pattern and housing depth mean a refit shop can pull X2s and bolt in X3s without modifying the transom, drilling new holes, or running new wiring. That's why DRSA sees so many upgrade orders rather than fresh installs.

SeaBlaze X3 vs X2 vs the Competition
The X3 doesn't exist in a vacuum. Yacht owners and refit shops also cross-shop the OceanLED Sport S3166s and the Hella Marine Apelo A2. Here's how they line up on the specs that drive purchase decisions.
| Feature | SeaBlaze X3 | SeaBlaze X2 | OceanLED Sport S3166s | Hella Marine Apelo A2 |
|---|---|---|---|---|
| Lumen output | 8,000 | 6,000 | 6,000 | 3,500 |
| Power draw at 12V | 5.5A, comparable to X2 | Baseline | Comparable to X2 | Lower (smaller fixture) |
| Housing | Solid naval bronze | Solid naval bronze | 316 stainless | Glass-reinforced composite |
| IP rating | IP68 | IP68 | IP68 | IP68 |
| Music sync | Yes (Poco) | No | No | No |
| Warranty | 5 years | 5 years | 5 years | 3 years |
| Drop-in X2 replacement | Yes (same hole pattern, same depth) | N/A (predecessor) | No | No |
Where the X3 Pulls Ahead
The X3 wins on lumen output and music sync. It's the only fixture in this group with the Poco Light-to-Sound capability. It's also the only one that drops into existing X2 holes at the same housing depth, which matters on every refit. On sealing, it matches the X2 and the OceanLED at IP68 rather than exceeding them, and its power draw sits in line with the X2 rather than undercutting it, so the upgrade case rests on brightness, control features, and installation simplicity rather than lower amp load.
How the SeaBlaze X3 Fits into a Full Lumitec Lighting System
Underwater lighting is one piece of a complete yacht lighting setup. The X3 sits inside a Lumitec ecosystem that covers navigation, anchor, deck, and interior.
Navigation Lights
The Lumitec Surface Mount Navigation Light pairs with the X3 on most yacht refits. It provides clear directional lighting that meets COLREG visibility requirements without the bulk of older fixed-mount nav lights.
Anchor Lights
The Lumitec Contour Anchor Light handles 360-degree visibility while at anchor. It's the standard pairing for yachts that overnight at anchorages around West Palm Beach and the Bahamas.
Poco System Integration
The X3's Light-to-Sound capability runs through the Lumitec Poco 4 controller (sold separately). One Poco can drive the X3 plus compatible deck lights and interior lights, syncing color and brightness across the whole boat. For yachts that entertain at anchor, this is the feature most owners cite as the deciding factor.
Installing the SeaBlaze X3 (and What to Expect on a Refit)
The X3 is a surface-mount fixture, meaning it bolts to the outside of the hull rather than threading through it. There's no through-hull penetration, no thermal well to drill, and no external driver box to mount inside the engine room.
The basic install is a 3-wire hookup: power, ground, and signal. The signal wire connects to a Poco controller if you're running music sync, or to a simple toggle if you're not.
On an X2-to-X3 upgrade, the install is straightforward: pull the old fixture, swap in the new one, reconnect the existing wiring. Most refit shops budget 30 to 45 minutes per fixture for the swap. On a fresh install, plan for hull layout, holesaw work, and sealing. That's a half-day to full-day job depending on yacht size.
DRSA recommends professional installation for any first-time install or for owners not comfortable with marine electrical work. We have a network of installers in the West Palm Beach, Stuart, and Fort Lauderdale corridor we can refer you to.
Who the SeaBlaze X3 Is For
The X3 is built for yachts in the 35 to 100+ ft range where underwater lighting is part of the boat's identity. Specific fits we see often at DRSA:
- Sportfish convertibles: Viking, Hatteras, Bertram, Merritt, Spencer, Jarrett Bay (40 to 80 ft)
- Express yachts and motoryachts: Sea Ray, Tiara, Carver, Marlow, Hargrave (40 to 80 ft)
- Mega yachts and explorer yachts: Westport, Hatteras 100, Christensen, custom builds (80+ ft)
- Performance center consoles where the owner wants underwater drama at the dock: Yellowfin, Invincible, SeaVee 390 and up
If you're running a smaller boat (under 30 ft), Lumitec's SeaBlaze Quattro or Zambezi Mini are usually a better match. The X3 is overkill for short transoms and small electrical systems.

Frequently Asked Questions
The Lumitec SeaBlaze X3 is a surface-mount underwater LED light for boats and yachts. It produces 8,000 lumens, is rated IP68, and is built with a solid naval bronze housing that requires no external driver. It's available in Spectrum RGBW and Dual Color White/Blue configurations.
Yes. The SeaBlaze X3 replaced the SeaBlaze X2 as Lumitec's flagship surface-mount underwater light. Lumitec discontinued the X2 when the X3 launched in early 2026.
The X3 produces more light output (8,000 lumens versus 6,000 on the X2) and adds Poco-compatible Light-to-Sound music sync, a feature the X2 didn't have. Housing depth, mounting pattern, and power draw are comparable between the two, which is what makes the X3 a straightforward drop-in upgrade.
Yes. The X3 uses the same mounting hole pattern and housing depth as the X2, so most refit shops can remove the X2 and install the X3 without drilling new holes or modifying the transom.
Light-to-Sound is a Poco controller feature that syncs the X3's color and brightness output to music or ambient sound. It requires a Lumitec Poco 4 controller, sold separately, and can also coordinate lighting across compatible deck and interior fixtures.
The SeaBlaze X3 carries a 5-year limited warranty from Lumitec. DRSA handles factory warranty registration on your behalf when you order through us.
Yes. The SeaBlaze X3 is rated IP68, which covers sustained submersion, and uses Lumitec's DryLock sealing technology for additional protection against moisture and leaks.
The SeaBlaze X3 draws approximately 5.5A at 12V, which is comparable to the SeaBlaze X2 it replaces. On 24V systems, draw is approximately 2.5A.
Yes. The SeaBlaze X3 runs on 10-30V DC, so it works on both 12V and 24V marine electrical systems without an external driver or converter.
The X3 is commonly installed on sportfish convertibles (Viking, Hatteras, Bertram, Merritt, Spencer, Jarrett Bay), express yachts and motoryachts (Sea Ray, Tiara, Carver, Marlow, Hargrave), mega yachts and explorer yachts (Westport, Hatteras 100, Christensen, custom builds), and performance center consoles (Yellowfin, Invincible, SeaVee 390 and up).
Most yachts in the 40 to 80 ft range run 4 to 8 fixtures spaced along the hull for even coverage; larger yachts and mega yachts often run 6 to 10 or more. Exact count depends on hull length, beam, and how much of the waterline you want illuminated. DRSA can help you work out a layout for your specific vessel.
The X3's 3-wire hookup and surface-mount design make it more straightforward than through-hull fixtures, and an X2-to-X3 swap is a simple fixture-for-fixture replacement. For a fresh install involving hull drilling and sealing, or if you're not comfortable with marine electrical work, DRSA recommends professional installation and can refer you to installers in the West Palm Beach, Stuart, and Fort Lauderdale corridor.
