Buying Guide
Key purchase considerations
- Base compatibility: E26 is common in many lamps and fixtures, while GU24 requires specific sockets. Check your fixture before purchasing.
- Wattage vs. lumens: A 13W CFL can produce around 900 lumens, typically replacing a 60W incandescent. If you need more brightness, consider higher-lumen options within the same base family.
- Color temperature: 2700K soft white provides warm, cozy light suitable for living rooms and bedrooms. For task lighting or kitchens, you may prefer 3000K or brighter options.
- Lifespan and energy savings: Look for rated lifespans around 10,000 hours and ENERGY STAR or UL certification for reliability and safety.
- Instant-on and flicker-free performance: These features improve user experience, especially for workspaces and reading areas.
Practical comparisons
- Costs and pack size: Packs of 2 or 3 bulbs offer economy when replacing multiple fixtures at once. Consider whether you need a spare bulb for future replacements.
- Fixture type and shade clearance: Spiral designs are compact and fit in tighter spaces, but check shade height and fixture depth to avoid obstruction.
- Color consistency: Ensure all chosen bulbs emit a similar warm tone to avoid mixed lighting in a room.
- Safety and certifications: UL-listed products provide peace of mind about electrical safety and performance.
