Lumishore’s ultra-slim thru-hull THX204 has a small hull cut out requirement of only 5/8” (16.5mm). The THX204 features 6,100 fixture lumens and an ultra-wide 110°beam angle, allowing the light to saturate deep into the water. With a simple 2-wire installation and no external drivers, it’s one of the easiest thru-hull lights to install and is suitable for transom, side hull or bottom installations. Control the THX204 by a standard on/off switch.
