Shadow-Caster SC3 Great White Underwater Light

The Shadow-Caster SC3 Series Great White Surface Mount Underwater Light provides your vessel with 24 watts of intense LED lighting. Designed with a sub-compact 3.6-inch outside diameter hard-anodized aluminum housing, it's built for under-the-waterline surface mounting in a small footprint.

A proprietary clear gel-filled design is injected through the entire unit to eliminate condensation and water intrusion under stress, paired with a tough, scratch-resistant tempered glass lens and hard-anodized aluminum housing impervious to acetone and solvents common in demanding marine environments. Transient surge and reverse polarity protection dramatically prolong unit life, and thermal throttling technology enables safe operation even out of water. It can be operated from a standard on/off switch, or paired with a compatible Shadow-NET controller for full-feature lighting control. Browse more in our marine lighting category.
