Model 04

A powerful thru-hull light in solid AB2 superyacht bronze, with a wide 110° beam, extensive color options and an interchangeable light engine serviced from inside the hull.

Sparkling White·5,760 lm

The best kind of luxury is not having to choose. Model 04 brings together lavish, beautifully uniform light, the broadest color palette we make, solid AB2 superyacht bronze and an interchangeable architecture designed for years of effortless ownership.

Some evenings deserve to last longer.

Model 04 fills the water around the yacht with a wide, inviting glow, turning a swim, a drink or a quiet hour at anchor into the part of the night nobody wants to leave.

Engineered to lead

What sets Model 04 apart.

Lighting

Impressive Lighting

A wide 110° beam fills the water around the yacht with a powerful, beautifully uniform glow — rich and expansive for unforgettable moments.

Color

The widest range we make

From Sparkling White, Deep Blue and Crystal Cyan to Wildlife Amber, Dual White/Blue and full RGBW — the broadest color range in the YPHOS collection.

Superyacht-grade AB2 Bronze

Made to Last

Precision-machined from AB2 superyacht bronze for exceptional corrosion resistance and lasting structural integrity in demanding saltwater environments.

Technology

Intelligence within.

More than a light source: behind the beam is a complete electronic system designed to keep Model 04 performing smoothly, safely and consistently for years.

Underwater lighting is a discipline of its own. Heat, salt water, confined spaces and sensitive onboard electronics place demands on a fixture that ordinary lighting systems never encounter. That is why we engineer our electronics in-house. Since 2007, we have been developing technology specifically for underwater lighting. The result is not simply a brighter light. It is an entire ecosystem with fixtures engineered as complete systems.

Built-in Drivers — high performance, high frequency, flicker-free and embedded drivers inside the fixture.

Active Thermal Control in 256 gradual levels. Model 04 constantly adapts its power to provide optimum lighting and prevent overheating.

EMC Certified and lab-tested to make sure that it doesn’t interfere with critical navigation or safety systems of your boat.

The evenings people remember.

Interchangeable thru-hull

Serviced from inside the hull.

Model 04’s interchangeable light module can be removed and replaced from inside the vessel while the bronze thru-hull body remains securely in place, avoiding haul-out or underwater servicing.

Control

Your whole vessel, from your palm.

Pair the RGBW version with the YPHOS Control app, WiFi Controller or MFD / DMX512 integration — set scenes, sync every fixture and dim the water to the mood of the night. Single-color versions run from a simple switch.
