Lumishore’s EOS TIX1603-CCP thru-hull RGBW underwater LED. 17,500 verified fixture lumens through a 110-degree ultra-wide beam, with the integrated-driver thru-hull architecture that lets you service the LED from inside the hull without dropping the boat.
The Lumishore EOS TIX1603-CCP Interchangeable Thru-Hull (MPN 60-0338) is Lumishore’s flagship RGBW thru-hull underwater LED in the EOS color-change architecture. The fixture delivers 17,500 verified fixture lumens of white output and 39,375 total LED lumens across the full color spectrum, through an ultra-wide 110-degree beam angle that creates the halo-effect water illumination that premium yachts use for evening dock displays and nighttime cockpit-to-water aesthetics.
What “interchangeable thru-hull” means. The TIX series uses an integrated internal LED array and driver inside the thru-hull body, which delivers a significant operational advantage over fixed-array designs. The LED array and driver can be serviced from inside the hull, so you don’t have to drop the boat or dive on the fixture to replace components when they fail. For yachts and serious cruising boats where the underwater LED fixtures live below the waterline for years between haul-outs, the inside-hull serviceability is genuinely meaningful for long-term ownership cost.
17,500 verified fixture lumens with HICOB array. The fixture uses HICOB (High-Intensity Chip-On-Board) LED arrays with the following configuration: 36 white LEDs at 10W each, 36 green LEDs at 3W each, 36 blue LEDs at 3W each, and 48 red LEDs at 3W each. The total LED lumens output is 39,375, with verified fixture lumens (the practical light output through the housing and lens) at 17,500 for white mode. For underwater illumination that needs to be visible at distance and in some daylight conditions, this is serious lumen output.
110-degree ultra-wide beam. The 110-degree beam angle delivers the halo-effect water illumination that’s the operational aesthetic for premium yacht underwater lighting. Narrower beam angles create concentrated spotlights that look more like dive lights than ambient illumination. The 110-degree beam spreads the light across a wide arc of water around the boat, which creates the distinctive halo glow that premium yachts use for evening entertainment and dock displays.
Full EOS color change (RGBW). The fixture cycles through the full RGBW color spectrum, with programmable scenes, color cycle with speed adjustment, color sweep with speed adjustment, customizable favorites, fixed and random strobes, sound-to-light response, and brightness adjustment. For owners and operators who want the full premium underwater lighting experience, the EOS color architecture delivers it.
MFD and WiFi control. The TIX1603-CCP is controllable directly from your MFD (certified marine MFD platforms (compatibility varies by chartplotter brand)), or the optional Lumishore Display, or via WiFi from a smartphone or connected device through the Lumishore app. Multiple lights synchronize automatically so you can run an entire boat’s worth of underwater LEDs in coordinated color and effect modes. Auto light discovery and setup simplify the commissioning process.
Programmable effects and modes. Customizable favorites let you save preferred color and effect combinations for quick recall. Programmable scenes deliver multi-step lighting sequences. Color cycle and color sweep effects with adjustable speed deliver dynamic illumination. Fixed and random strobe modes add nightclub-style effects. Sound-to-light responds to onboard audio for synchronized lighting and music. For owners who want the full programmable underwater lighting experience, the TIX1603-CCP delivers the full feature set.
Marine-grade construction. The housing is marine-grade aluminum bronze with borosilicate glass lens, sized for continuous submersion in saltwater service. The architecture is designed for transom, side, or bottom mounting depending on the desired illumination pattern. For boats where the underwater LEDs need to operate continuously in saltwater for years, the construction and materials are sized for the operational duty.
Plug-and-play connections. The supplied cabling uses plug-and-play connectors that simplify installation versus traditional wire-stripping and connection-block setups. The fixture ships with two 1-meter DMX cables (part 60-0403) and the supporting hardware for typical thru-hull installation.
Typical LED life 50,000-plus hours. The LED service life rating at 50,000-plus hours of operation translates to multiple years of typical use even on charter operations and high-use vessels. The 3-year warranty backs the build quality. For yachts where the underwater LEDs are installed and expected to operate reliably for the life of the boat ownership, the service life and warranty are meaningful.
Power supply requirements. The fixture operates on 24V DC supply with maximum current draw of 6.5 amps. For 12V boats, a voltage converter or 24V auxiliary system would be required. For yachts and larger vessels with 24V house systems (common in this boat size class), the supply matches the boat’s electrical architecture.
Install considerations. Underwater LED thru-hull installation is a yard-grade job. The thru-hull penetration must be properly cut, sealed, and bonded with appropriate marine-grade fittings. The fixture mounts in the thru-hull with the housing watertight to the hull, the LED array assembly accessible from inside. Electrical install requires 24V DC supply sized for the 6.5A current draw plus appropriate fusing, plus the data cabling for MFD and WiFi control integration. Total install is a marine yard or experienced installer multi-day job per fixture for a fleet of LEDs. Plan to install during a haul-out for the thru-hull cutting and sealing portion.
Why pay this much. Three reasons. First, 17,500 verified fixture lumens through a 110-degree beam is the lumen-and-beam combination that delivers the halo-effect aesthetic premium yachts use, not a recreational-grade fixture that looks dim against the water at this scale. Second, the interchangeable TIX architecture with inside-hull LED array serviceability is a meaningful long-term ownership advantage for yachts where the lights are below the waterline for years between haul-outs. Third, the full programmable EOS color architecture with MFD, Display, and WiFi control plus light synchronization delivers the premium underwater lighting experience that the rest of the yacht is built to. For owners building serious yacht underwater lighting, the TIX1603-CCP earns its position.
