Key specifications

Compatibility & control

The ORA THX204 is a single-color light controlled by a standard third-party on/off switch only. Smart controller integration (i-Connect, EOS-Link, Lumi-Link, NMEA 2000, MFD) is not available for this model — those features are exclusive to the SUPRA dual-color and EOS full-color series.

• Control method: on/off switch (third-party supplied) — simple 2-wire connection
• No external driver required: driver is built into the light body
• Hull isolation kit: available separately for metal, aluminum, or carbon fibre hulls

Confirm hull thickness, internal clearance, bonding, and cable run length before installation.

Frequently asked questions

Does the ORA THX204 White work with a Garmin chartplotter?
No — the ORA THX204 single-color series is on/off switch controlled only. MFD integration via i-Connect, EOS-Link, or NMEA 2000 is not supported. For MFD-controlled lighting, see the SUPRA THX404 or EOS series.

What is the hull cutout size?
The THX204 requires only a 16.5 mm (5/8”) perpendicular hole — the smallest of any Lumishore thru-hull. Profile protrudes 18 mm (0.71”) above the hull surface.

How does the THX204 compare to the TIX204?
Both are ORA single-color thru-hull lights with built-in drivers. Key differences: the TIX204 has an interchangeable LED module serviceable from inside the hull; the THX204 has a smaller 5/8” cutout and a wider 110° beam. Choose THX204 for smallest cutout; choose TIX204 if serviceability without haul-out is a priority.

Is the THX204 IP68 rated?
Yes — IP68 for continuous submersion in marine bronze housing with Borosilicate toughened glass lens.

What size vessel is the THX204 rated for?
Lumishore rates the THX204 for vessels up to 24 m (80 ft). Suitable for transom, side-hull, and bottom mounting.

Is this a Garmin product?
Yes. Garmin acquired Lumishore in October 2024. The ORA THX204 White carries Garmin MPN 010-04515-00 and is sold through Garmin-authorized dealers including MyGreenOutdoors. Hardware and design are unchanged.

What warranty does the THX204 carry?
A 3-year warranty covers defects in workmanship from the date of original purchase.
