Lumitec SeaBlaze X2 vs X3: What Changed and Which to Buy
The SeaBlaze X2 and the SeaBlaze X3 are Lumitec’s surface mount underwater lights, and because the X3 arrived as the direct evolution of the X2, boat owners keep asking the same question: is the newer one worth it, and does the older one still make sense? Both are in stock in Pompano Beach, so this comparison uses the manufacturer’s own specifications, side by side.
The short answer
The X3 is the more capable light: more output, a longer warranty and support for Lumitec’s Poco digital control system. The X2 remains a proven performer with the same footprint and the same simple installation, and it is the one to pick if you prefer its polished housing or find it at a better number. Neither choice requires different holes in the boat, because the two share the same dimensions and mounting.

Both lights run Lumitec’s Timed Toggle Protocol for mode switching from the existing switch, and neither supports third party dimmers. Both are built of marine grade bronze and heat tempered glass and are designed and manufactured in the USA.
Where the X3 pulls ahead
Output. 8,000 lumens against 6,000 is a full third more light for about five watts more. If the goal is the biggest glow behind the transom, this is the headline difference.
Warranty. Five years against three is the manufacturer’s own statement of confidence in the new platform.
Sealing. The X3 is the first Lumitec light with DryLock, the company’s system combining thermal management, leak protection and moisture prevention.
Poco. The X3 is compatible with the Lumitec Poco digital lighting control system. If you run or plan a Poco setup, the X3 is the one designed to join it.
Where the X2 still makes sense
The X2 was the light the competition chased for years, and nothing about the X3 launch changed what it does on a transom. It shares the exact footprint and mounting of the X3, comes in the same two color versions, and its polished housing is the brighter finish of the two. If the extra output and the Poco ecosystem are not on your list, the X2 delivers the proven SeaBlaze experience.
Which one should you buy?
- Buy the X3 if you want the most output, the longest warranty, or Poco digital control: SeaBlaze X3 Spectrum or SeaBlaze X3 Dual Color White/Blue.
- Buy the X2 if you prefer the polished housing or the price works in its favor: SeaBlaze X2 Spectrum or SeaBlaze X2 Dual Color White/Blue.

Frequently Asked Questions
What is the difference between the SeaBlaze X2 and X3?
The X3 produces 8,000 lumens against 6,000 on the X2, carries a 5 year warranty against 3 years, adds DryLock sealing and Lumitec Poco compatibility, and draws slightly more power. The size, the surface mount design and the half inch cable hole are the same on both.
Are the SeaBlaze X2 and X3 the same size?
Yes. Both measure 3.94 inches in diameter and 0.85 inches deep, surface mount to the transom and need only a half inch hole for the cable, so they occupy the same footprint on the boat.
Is the SeaBlaze X3 compatible with the Lumitec Poco system?
Yes, the X3 is Poco system compatible. The X2 does not list Poco compatibility in its specifications, so if you plan to run digital lighting control, the X3 is the one built for it.
Does the SeaBlaze X3 use more power than the X2?
Slightly. The X3 is rated at 65 watts and draws 5.5 amps at 12 volts, against 60 watts and 5 amps on the X2. Both run on 10 to 30 volts DC, so the difference rarely changes the wiring plan.
