Neptune X6 Through-Hull Underwater LED Light
Low-profile SAE 316L stainless-steel underwater lighting for demanding marine installations.
Low-Profile Stainless-Steel Underwater Lighting
The Neptune X6 is a low-profile through-hull underwater LED light designed for boats requiring a durable, corrosion-resistant stainless-steel fixture. Its SAE 316L stainless-steel unibody, thick tempered-glass lens, integrated thermal management, and protected electronics are designed for demanding below-waterline installations.
The fixture projects only ~5mm beyond the hull and uses a 100mm outer bezel, providing a clean installation with a relatively small exterior footprint.
The blue model provides vivid underwater accent lighting while maintaining low electrical demand.
High-performance through-hull underwater lighting in a compact stainless-steel housing. The Neptune X6 combines useful underwater illumination, a low-profile exterior design, and rugged stainless-steel construction.
Six 5W Cree® LEDs provide efficient underwater illumination. High-intensity blue light provides vivid underwater accent illumination. Instant-on illumination with no warm-up time.
The SAE 316L stainless-steel housing is highly resistant to corrosion in marine environments and does not use a separate sacrificial anode as part of the fixture assembly. Installation must still follow proper bonding, isolation, sealing, and corrosion-control practices appropriate to the vessel and hull material.
Rugged construction with no fragile filament supports long service life and shock- and vibration-resistant performance.

Installation Requirements
- Installation must be performed by a qualified marine technician.
- Confirm adequate access inside the hull before drilling.
- Required hull opening is ~68mm.
- Maximum hull thickness must not exceed the specified limit.
- Use an appropriate marine-grade below-waterline sealant.
- Confirm compatibility with the vessel’s hull material.
- Use a 3A slow-blow fuse per light and appropriately sized marine wiring.
- Keep the lens free of paint and marine growth.
- Follow the full installation manual.
Maintenance
Keep the glass lens clean and free from paint, marine growth, and debris. Use only non-abrasive cleaning tools suitable for glass. Periodically inspect the housing, seal, wiring, and connections for damage or deterioration.
