Buying Guide
- Post size compatibility: Most posts fit standard 4×4 wooden or vinyl posts, with adapters for 3.5×3.5 or 5×5 options. Measure post dimensions and check whether adapters are included or sold separately.
- Color and brightness options: Look for models with warm white for ambiance and cool white for task lighting. Some lights offer 2 brightness levels per color to tailor the output to your space.
- Power and installation: All listed options are solar-powered and do not require wiring. Confirm the solar panel size and the included mounting hardware for your post material (wood vs. vinyl).
- Weather resistance: Prioritize IP or IPX ratings and material quality for rain, snow, wind, and sun exposure. IP64 or IP65 is common among outdoor caps.
- Bundle size and coverage: If you need multiple posts lit, consider multi-pack options (4, 6, 10, or more) to achieve consistent lighting across fences, decks, and mail areas.
- Aesthetic and fit: Controllerless caps with modern housings look best on contemporary fences and decks, while traditional styles may suit classic posts better. Ensure the base design matches your post diameter and exterior finish.
