Shadow-Caster SC3 Series Bimini Blue Aluminum Pontoon Mount Underwater Light

The SHADOW-CASTER™ SC3-ALTB is a 3" underwater pontoon light engineered specifically for bracket mounting on aluminum-hulled vessels. Its compact diameter and single-bolt installation design integrate seamlessly with pontoon boat infrastructure. The scratch-resistant tempered glass lens paired with hard anodized aluminum housing resists chemical degradation from acetone, solvents, and corrosive saltwater exposure. The proprietary gel-filled core is injected throughout the entire unit, establishing a robust moisture barrier that eliminates condensation and water intrusion under operational stress. Built with American manufacturing standards, this fixture delivers the durability and performance pontoon boat owners demand in demanding marine environments.
