What I Look for Before Buying
Before I choose any solar post cap, I always check a few important things:
- Fit: I make sure the cap is made specifically for 6×6 posts so it sits securely.
- Material: I prefer durable materials like aluminum, stainless steel, or weather-resistant plastic.
- Brightness: I look for enough light to be useful, but not so bright that it feels harsh.
- Battery Life: I want a cap that can stay lit for several hours after sunset.

- Decorative Lantern-Style Caps: I like these when I want a more elegant or traditional appearance.

Final Thoughts
