Add powerful underwater illumination and sleek style to your boat with the Attwood LightArmor HPX Underwater Light. Designed for durability and performance, this HPX model features three high-output blue LEDs that produce a vibrant glow while improving nighttime visibility around your vessel.
Built with a fully sealed, marine-grade housing, the LightArmor HPX is engineered to withstand harsh saltwater and freshwater environments. Its low-profile surface-mount design allows for clean transom installation without complex hull modifications, making it an excellent upgrade for a wide range of boats.
Energy-efficient LED technology delivers long service life with minimal power draw, providing reliable underwater lighting season after season.
Key Performance Features
-
Extreme 1,350 Lumens: Offers roughly 68% more light output than the standard 4.0 HP model, creating a much larger and more vivid Sapphire Blue glow.
-
Intelligent Thermal Management: Features the Exclusive Heat-Sync Cooling System with active overheat protection. If the light is accidentally left on out of water, it will automatically dim to protect the LEDs.
-
Universal Voltage: Fully compatible with both 12V and 24V DC boat systems.
-
Military-Grade Durability: Built with a fully-potted (resin-sealed) electronic board, a thick impact-resistant lens, and a polished 316 stainless steel bezel.
-
Low Profile Design: At only 0.59″ thick, it sits nearly flush to the hull, minimizing drag and the risk of catching on trailer bunks.
