Buying Guide
Key considerations when choosing 8-inch round fluorescent bulbs for circline fixtures:
- Color temperature: Choose daylight (around 6400–6500K) for task lighting and kitchens; choose cool white (4100K) for general use; warm white (3000K) for living areas.
- Lumens and brightness: 1250–1350 lm is common for 8″ 22W bulbs; larger 32W bulbs in 12″ sizes provide higher lumens but may not fit every fixture.
- Base compatibility: Most listed bulbs use G10q 4-pin bases. Confirm your fixture’s base before purchasing.
- Cri and color rendering: CRI 80+ indicates decent color accuracy; higher CRI is preferred in kitchens and workspaces.
- Fixture size and compatibility: Some bundles include both 8″ and 12″ bulbs; ensure your ceiling mount or fixture diameter can accommodate the bulb size.
- Energy usage and life: 22W bulbs are common; 12,000+ hour lifespans are typical for professional-grade options but verify product data when possible.
