Shadow-Caster Ultra Blue Single Color Underwater Light - 16 LEDs - Bronze

The Shadow-Caster Ultra Blue Single Color Underwater Light with 16 LEDs in bronze is a high-intensity submerged lighting solution engineered for serious marine applications. Delivering 6,700 lumens of deep blue illumination, this fixture transforms underwater visibility for nighttime boating, fishing, and dock operations. The ultra blue spectrum cuts through saltwater and freshwater conditions to maximize target visibility while creating the signature aesthetic that discerning boaters demand.

Built for durability in harsh marine environments, the fixture features a slim 0.63-inch profile and 4-inch diameter that allows discreet mounting on hulls, transducers, or underwater structures without disrupting hydrodynamics. Surge and reverse polarity protection safeguard against electrical spikes common in saltwater installations, while transient surge protection extends operational lifespan. Thermal throttling technology allows safe operation out of water during maintenance or storage. Optional dimming and strobe control features provide flexibility for different lighting scenarios—from subtle ambient night operation to high-visibility distress signaling.

Weekend anglers and serious offshore operators alike rely on this fixture for improved fish attraction, safety lighting, and dock-side visibility. The bronze housing resists corrosion better than unpainted aluminum in salt spray conditions, making it ideal for long-term deployment on coastal vessels. Whether you're running night fishing expeditions, improving navigation safety, or setting up permanent underwater lighting systems, this Shadow-Caster delivers the output and engineering reliability that working boats require.

The 16-LED array ensures even light distribution and redundancy—individual LED failure does not black out the entire fixture. This architecture appeals to boaters who operate far from service facilities and need lighting systems that degrade gracefully rather than fail completely.
