Buying Guide
What to consider when choosing an onion lamp post light:
- Post type and mounting: Determine whether you need a post, pedestal, or pier-mount fixture and confirm post diameter or mounting compatibility.
- Material and finish: Brass, iron, and steel offer different durability and weather resistance. Finishes like bronze, aged zinc, or black complement varied facades.
- Glasses and glow: Seeded glass softens illumination while clear glass can provide brighter light. Seedy or clear glass affects glare and ambiance.
- Bulb type and compatibility: Check whether the fixture supports LED, CFL, or incandescent bulbs and confirm wattage limits (often up to 60W).
- Water resistance: Look for wet-rated or weatherproof certifications for outdoor use in rain and snow.
