Buying Guide
What post size do I need to fit? Most lights target 4×4 posts or 3.5×3.5 posts with adapters. Measure actual post dimensions and check compatibility notes before buying.
What color temperature should I choose? Warm White creates a cozy vibe; Cool White offers crisper, security-like brightness; Neutral White is a balanced option for general use.
Do I want a higher number of LEDs or a specific lighting pattern? More LEDs generally provide more even coverage. Some lights feature decorative flames or a modern flat lens for uniform glow.
How important is solar charging time? Look for longer daylight charging windows for better dusk-to-dawn performance, especially in shorter winter days or cloudy climates.
Is the product suitable for vinyl, wood, or both? Some caps fit vinyl and wood differently; confirm mount compatibility and any required adapters.
Ease of installation: Most units are designed for tool-free mounting, but some may require additional hardware or bundles for exact post sizes.
