Overview

The Lumitec Zambezi X2 is a surface-mount underwater light that puts 6,000 lumens on the waterline without needing a recessed can or a large hull cutout.

It runs on 10-30 VDC for 12V and 24V systems and draws 5A at 12V DC or 2.5A at 24V DC, so it fits typical dedicated lighting circuits when you size wiring and protection correctly. The light body measures 4 in (10.16 cm) in diameter and 1.6 in (4.06 cm) deep, which helps when you are working around brackets, strakes, trim tabs, or tight interior clearances.

The housing is bronze and IP68 rated for continuous submersion. Control can be as simple as on and off with Timed Toggled Protocol (TTP) for color selection from a standard switch, or it can be integrated into a Poco Digital Lighting Control setup when a Poco module is used.

Key features

• 6,000-lumen output with dimming support through compatible control
• 10-30 VDC input for 12V and 24V electrical systems
• Current draw: 5A at 12V DC, 2.5A at 24V DC (60W)
• Surface-mount form factor: 4 in (10.16 cm) diameter, 1.6 in (4.06 cm) depth
• IP68-rated housing for continuous submersion
• Naval bronze housing with a built-in isolating spacer to help reduce galvanic corrosion on aluminum installations
• TTP control for color selection from a standard on and off power switch
• Poco system compatible (PLI enabled) for advanced control through a compatible MFD or the Lumitec Poco app when paired with a Poco module
• Not compatible with third-party dimmers; CE certified; 3-year warranty

Variants

This product is offered in multiple light-color configurations.

The differences are in the output mode (dual-color versus full-color Spectrum). Power range, current draw, housing finish, size, and IP rating remain the same across the listed configurations.

• 101708: Light color White/Blue. Switch between crisp white for docking and deck-side work and blue for a lower-glare look on the water.
• 101700: Light color RGBW Spectrum. Provides full-color control plus a dedicated white channel for clean whites when you do not want a tinted output.

Installation and setup

As a surface-mount underwater light, the body mounts externally on the transom, hull side, or pontoon log where it can wash the water behind the boat. Plan for a solid, flat mounting area and keep the lens clear of trim-tab travel, steps, and trailer bunks. The 1.6 in depth is helpful when access behind the mounting surface is limited.

Wiring routing depends on the build. Some installations run the cable along the surface to existing chases, while others pass wiring through the structure to the inside of the boat. Any hull penetrations and fasteners should be sealed properly for below-waterline service.

Electrical and control

Use a dedicated circuit sized for up to 5A per light on 12V systems. Keep cable runs in mind when selecting wire gauge to avoid voltage drop, especially on longer runs to the transom. This light does not accept third-party dimmers, so dimming and advanced scene control should be handled through compatible digital control, while basic color selection can be done through TTP using a standard switch.

Compatibility and fit

The 10-30 VDC input range makes it suitable for most 12V and 24V boats. The built-in isolating spacer is particularly useful when mounting on aluminum pontoons or other aluminum structures where galvanic isolation matters.

On-board use

This light is a good match for pontoon boats, wake boats, and cruisers that want strong underwater illumination for dockside nights, swimming, and aft visibility. It also fits boats that prefer a surface-mount approach due to limited interior access or because they want to avoid large hull cutouts.

Maintenance and care

Rinse the light after saltwater use and avoid abrasive pads on the lens. Periodically inspect the mounting hardware and any sealing points, and clean marine growth as needed to keep output consistent.
