High-output white lighting from a compact thru-hull fixture

The Lumishore THX204 White provides dedicated white underwater illumination for vessels that do not require dual-color or RGBW lighting. Its 6,100 fixture lumens are distributed through an ultra-wide 110° beam, providing broad illumination around the stern, hull side or bottom of the vessel.

The thru-hull design combines a compact exterior face with a small mounting opening. Its marine-bronze body and borosilicate glass lens are designed for submerged marine use, while the 10.5–31 VDC operating range accommodates both 12V and 24V electrical systems.

Dedicated white underwater illumination

The THX204 White is designed specifically for white output rather than selectable colors or RGBW effects. This makes it suitable for installations where consistent white underwater lighting is required without the additional control architecture associated with multi-color systems.

The 110° beam provides wide light distribution, while the 6,100 fixture-lumen output gives the THX204 a defined performance level within Lumishore’s thru-hull lighting range.

Thru-hull installation considerations

Installation requires a 0.65 in (16.5 mm) mounting opening and approximately 3.78 in (96 mm) of clearance behind the mounting surface.

Before installation, confirm the available interior depth, cable routing, circuit protection, hull construction and mounting location. Each fixture should be individually protected according to the applicable Lumishore installation instructions.

Before You Order

  • Confirm that dedicated white output matches the intended lighting setup.
  • Verify that the vessel operates within the 10.5–31 VDC range.
  • Check the required 16.5 mm mounting opening and interior clearance.
  • Confirm hull construction and installation requirements.
  • Plan fixture placement around the ultra-wide 110° beam.
  • Verify the required driver and electrical components for the installation.
