Buying Guide: Key Considerations for 12V Interior Lighting
What should you look for when choosing 12V interior lights for vehicles and boats?
- Brightness and spread: For small spaces, 300–550 lumens per fixture with a diffuse lens prevents hotspots. For larger areas, consider 800–1100 lumens or multiple fixtures.
- Voltage compatibility: Most RV lights support 12V and some 24V or 12V-24V hybrids. Confirm your vehicle or boat’s voltage system before purchase.
- Durability: Look for heat-resistant materials, corrosion resistance, and IP ratings if exposed to moisture or wash-downs. IP68 is ideal for wet or marine environments.
- Power efficiency: LEDs offer long life and low power draw. Check life expectancy and wattage to estimate runtime on battery power.
- Installation: Consider whether the fixture is surface-mount or recessed. Include mounting hardware and wiring requirements in your plan.
- Control options: Independent side lighting or single-switch setups provide flexibility. Consider dimming or multi-way switching if you need varied brightness.
