Buying Guide: Key Considerations For Exterior Marine Courtesy Lights
What should you prioritize when choosing marine courtesy lights? Start with waterproofing and durability, then color options, power usage, and mounting flexibility. Consider your boat size, typical weather, and wiring setup to ensure compatibility and easy installation.
- Waterproofing and durability: Look for IP68 ratings and corrosion-resistant materials such as stainless steel housings and hard PC backs to withstand saltwater and vibration.
- Color options: RGBW lights offer color versatility for ambiance and signaling, while white-only lights simplify operation and conserve power.
- Power and wiring: Check the voltage (commonly 12V), current draw, and whether the lights require dimmers or special switches. Surface mount vs recessed mount affects installation complexity.
- Mounting and fit: Ensure hole size or bezel diameter matches your deck or cabin layout. Recessed designs provide a cleaner look, but require precise cutting.
- Light distribution: Consider lens quality and LED density to achieve uniform illumination on decks, steps, and railings.
