Buying Guide
Key considerations when choosing bayonet to screw adapters:
- Compatibility: Verify the socket type (B22 vs. GU10) and the target bulb base (E26 vs. E27) before purchase. Some adapters convert between multiple screw sizes; others are specific to one pair.
- Voltage and Wattage: Ensure the adapter supports the voltage range in your region (commonly 100-250V AC in many areas) and a wattage ceiling that covers your bulbs (often up to 60–200W).
- Material and Build: Metal bodies with heat-resistant shells (PBT or flame-retardant polymers) tend to offer better durability and insulation, reducing heat buildup in enclosed fixtures.
- Installation Ease: Look for adapters that snap or screw in securely without tools, minimizing wobble and ensuring a tight fit with no looseness.
- Safety Certifications: CE, RoHS, and similar certifications indicate conformance to safety and environmental standards. Ensure adapters meet applicable requirements for US installations.
- Bulk and Cost Considerations: Multi-pack adapters can be economical for households replacing several fixtures. Check if the pack size aligns with your project scale.
- Fixture and Aesthetic Fit: Consider the adapter’s size and shape to ensure it fits within the fixture’s housing and does not protrude excessively or obstruct other components.
- Longevity and Durability: Materials that resist aging and temperature fluctuations contribute to longer life, especially in high-use areas like kitchens and living rooms.
