Buying Guide
- Base type and size: Confirm whether your fixture uses E26 (standard) or candelabra E12 bases. A mismatch can prevent proper fit or dimming capability.
- Brightness and color temperature: Choose between soft white (2700K–3000K) for cozy spaces or daylight (5000K–6500K) for task lighting and kitchens. Dimmable options offer flexibility for mood lighting.
- Energy efficiency and lifespan: LED bulbs consume less energy and last significantly longer than incandescent equivalents. Consider long-term savings alongside upfront cost.
- Dimming compatibility: If your ceiling fan has a dimmer switch, select dimmable bulbs and check compatibility with your dimmer model to avoid flicker or limited dimming range.
- Globe vs. candle shape: Globe (G25/G45) shapes provide a contemporary look, while candle shapes (A15 or B10) emphasize decorative fixtures and fans with glass shades.
- Color Rendering Index (CRI): Higher CRI (close to 90-100) yields truer colors, which is beneficial in living and dining areas where color accuracy matters.
- Indoor vs. outdoor use: If the fixture is exposed to the elements, verify suitability for outdoor or enclosed fixtures as labeled by the manufacturer.
- Voltage and compatibility: Most residential bulbs operate at 120V in the U.S. Ensure the bulb’s voltage rating matches your home’s supply.
- Fixture compatibility: Some ceiling fans have integrated light kits with specific sockets or wattage limits. Check the fan’s manual for maximum wattage per bulb and total for the circuit.
