Buying Guide
Key considerations for choosing solar post cap lights:
- Post size compatibility: Confirm exact post dimensions (especially 3.5×3.5 vs 4×4) before purchasing to ensure a secure fit.
- Weather resistance: Look for IP ratings (IP44, IP64) and materials that withstand UV exposure, rain, and snow.
- Light color and brightness: Decide between warm white for ambiance or cool white for visibility, and consider brightness levels for runtime.
- Power and battery: Check LED count and battery capacity; more LEDs can mean higher brightness but shorter runtime in cloudy conditions.
- Installation: Prefer tool-free mounting when possible; verify included adapters for composite post types (wood vs vinyl).
- Aesthetic fit: Consider design style (modern, rustic, decorative flame) to match your deck or fence decor.
