Buying Guide — Key Purchase Considerations
- Waterproof rating and depth usage: Most items use IP68. Confirm depth ratings and marine sealing to ensure long-term performance.
- Beam angle and brightness: Wider angles increase coverage; higher lumen outputs deliver more visibility but may illuminate unintended areas.
- Materials and corrosion resistance: 316L stainless steel and high-grade PC or ASA housings resist saltwater and UV exposure.
- Voltage compatibility: 12V and 24V systems are common; ensure compatibility with your boat’s electrical setup.
- Installation considerations: Some lights require holes, screws, or glue; ensure mounting surfaces are prepared and sealed properly.
- Color options: RGB lights offer mood and signaling versatility; single-color blue or white options are often simpler and more economical.
- Maintenance and service life: Look for long-life LEDs and proven seals; consider warranty when evaluating total cost of ownership.
