Buying Guide
What size is your post? Most Classy Caps caps fit 3.5×3.5 or 4×4 posts, with some models accommodating larger sizes. Check adaptor availability and included fittings before purchasing.
Light color and mode: Choose warm white for a welcoming glow or cool white for modern clarity. Some models offer dual modes and auto-on features, which enhance nighttime usability without energy waste.
Battery life and charging: Look for rechargeable Ni-MH or Li-ion cells and a dusk-to-dawn sensor. Longer runtimes extend evening lighting, but rely on sufficient daytime sun exposure for full charge.
Material and durability: Cast aluminum caps resist corrosion and weathering. Glass lenses produce crisper light but may require careful cleaning. Consider caps with waterproof seals for longevity in rain-prone areas.
Installation and compatibility: Ensure the cap sits securely on your post diameter and height. Some caps are universal with adaptors; others are post-size specific. DIY-friendly models save time and effort.
Maintenance and aesthetics: If you want a high-end look, models with real glass or stained-glass accents provide a premium appearance. For practical prioritization, focus on brightness, battery life, and auto functionality.
