Attwood LightArmor HPX 3-LED Blue Underwater Light

Description

This 4-inch Attwood LightArmor HPX (Extreme High Performance) Underwater Light packs 3 LEDs in blue, built with the latest technology to deliver long life cycles, minimal heat buildup, and real brightness rather than a fixture that dims after a season of use. The sleek, low-profile housing needs minimal mounting hardware to install.

A dedicated heat-sink cooling design with built-in overheat protection keeps the electronics from running hot during long stretches of use, and reverse polarity protection means a wiring mistake during install won’t take the light out. Fully sealed, waterproof electronics and an impact-resistant lens round out a build that’s engineered for long-term marine durability.

It works on both 12V and 24V DC systems, resists corrosion, chemicals, and UV damage, and ships with 3 feet of sheathed wire. An electro-polished 316 stainless steel cover is available as an OEM option, and the whole fixture carries CE certification.
