Buying Guide
What should I consider before buying underwater lights?
Waterproof rating matters. Look for IP68 for full submersion. Consider material: 316 stainless steel offers strong corrosion resistance for saltwater use. Check beam angle: 120°–180° provides broad coverage, while narrower angles reach farther.
How many lights do I need and where to install them?
For pontoons, two to four lights per side around the transom or stern is common, depending on deck size. Install near mounting points to minimize glare into the cabin and maximize water illumination.
What about power and electrical compatibility?
Most marine lights run on 10–36V DC or 12–36V DC. Choose lights matching your boat’s electrical system. Be mindful of runtime and wire routing to avoid overloading circuits.
Durability and maintenance: what to expect?
Look for robust housings (316 stainless steel) and sealed backings. Marine-grade silicone or glue helps prevent leaks. Routine inspections for corrosion and seal integrity extend service life.
Installation tips for pontoons
Use stainless hardware and sealant rated for marine use. Ensure cables are secured away from propellers and moving parts. If wiring through the hull, plan for strain relief and water ingress protection.
