Dr. LED Through-Hull Mounted Underwater LED Light


SKU: Neptune Category:


The Neptune is a general purpose through-hull mounted LED light with three US made high-flux LEDs. This light is fabricated from the highest quality components to assure long life and trouble-free functioning. The aerospace-grade anodized aluminum composite body makes it extremely corrosion proof and the surface as hard as steel.

Their patented internal circuitry provides consistent brightness and makes them immune to life-shortening voltage fluctuations. Their incredibly low power draw (~1A @ 12V) makes them the perfect way to reduce energy consumption.
