SC3 - Great White

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 integrate seamlessly with pontoon boat infrastructure. The scratch-resistant tempered glass lens paired with hard anodized aluminum housing resists chemical degradation from acetone and solvents in demanding environments. 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 reliable performance for pontoon boats. Note: The SC3-ALTB is designed for freshwater use on trailer and lift-kept boats only.
