Buying Guide
- Decide whether you need interior mood lighting, deck visibility, or transom downlighting. Higher lumens help at night for activity-heavy tasks, while mood lighting emphasizes ambiance.
- Verify your boat’s electrical system (12V typical, some 24V setups). Choose products with compatible voltage ranges or multi-voltage options.
- IP67/IP68 are common; IP68 offers stronger water protection for immersion scenarios. Consider placement near bilge or spray areas.
- Look for stainless steel housings (304 or 316) and tough PC lenses to resist saltwater and corrosion.
- Surface-mount vs recessed; ensure mounting surface compatibility and gasket integrity to prevent leaks.
- High-lumen units provide brighter scenes but may consume more power. Balance brightness with battery or power supply capabilities.
- Blue LEDs are popular for night vision and nautical ambiance, but ensure color consistency across multiple fixtures for a uniform look.
- Consider ease of cleaning and accessibility for wiring in case of future service needs.
