B22 Bayonet Cap LED Bulbs, the Traditional British Fitting Across Every Form

B22 is the standard bayonet cap, the traditional British connection type that remains the most common base in older UK homes and a significant proportion of newer fittings. If a ceiling pendant, floor lamp, or table lamp uses a push-and-twist connection, it is most likely B22.

Dulora's B22 range covers GLS (A60), candle (C35), fancy round (G45), globe (G95, G125), and Edison (ST64) forms across Extra Warm 2200K, Warm White 2700K, and Soft White 3000K. CRI 90 to 97+ across the range, with select premium models reaching CRI 97+ for near-perfect colour rendering.

All 230V dimmable models work with a quality trailing-edge LED dimmer LED Light Dimmers. For the E27 screw alternative, see E27 Bulbs. For the GLS range, see GLS Dimmable.

B22 Bulbs: The Traditional British Base Across Every Bulb Form

Is B22 or E27 more common in UK homes?

B22 remains more common in older UK properties and is still widely used in new fittings. E27 is increasingly standard in imported and contemporary fittings. Many UK homes contain a mix of both. Dulora offers the full range in both base types, so the choice is determined by the fitting rather than the product availability.

The practical advice: check each fitting individually rather than assuming all fittings in a home use the same base.

Is B22 the same as BC?

Yes. B22 is the technical designation (Bayonet 22mm). BC (Bayonet Cap) is the common UK name. The terms are interchangeable. Both refer to the standard 22mm bayonet connection with push-and-twist action.
