Buying Guide
What to consider when choosing a boat light bar box:
- Beam pattern: Spot focuses forward distance; flood covers nearby surroundings. For open-water night navigation, a combo beam is typically best.
- Length and mounting: Longer bars offer broader coverage but require more mounting space. Ensure clearance under rails and around hardware.
- Water resistance: Look for IP ratings (IP67, IP68) and corrosion resistance for saltwater use.
- Power and wiring: Check wattage, voltage compatibility (12V or 24V), and whether a wiring harness is included for easier setup.
- Durability: Aluminum housings and reinforced seals improve longevity in harsh marine conditions.
- Installation considerations: Bracket adjustability helps align beams precisely; consider vibration and mounting strain on the boat frame.
