This 10-pack includes two color modes (warm and cool) and 16 LEDs to deliver a soft, diffused glow suitable for decks and fences. It’s designed for standard 4×4 posts and includes mounting hardware.

Buying Guide
Key factors to consider when choosing solar post cap lights:
- Post fitting: Confirm your post dimensions (4×4 or 3.5×3.5 inches). Some products do not fit other sizes.
