B22 LED 灯泡

B22 is the standard bayonet cap, a widely used connection type found in many homes. If a ceiling pendant, floor lamp, or table lamp uses a push-and-twist connection, it's most likely B22.

B22 Bulbs: The Bayonet Base Across Every Bulb Form

How do I know if my fitting uses B22 or E27?

B22 uses a bayonet connection, push in and twist to lock. E27 uses a screw connection, twist continuously in one direction. Many homes contain a mix of both. Dulora offers the full range in both base types, so the choice comes down to the fitting rather than product availability.

Is B22 the same as BC?

Yes. B22 is the technical designation. BC (Bayonet Cap) is a common name for the same base. Both refer to the standard 22mm bayonet connection with push-and-twist action.
