B22 lamp caps for led bulbs


B22 Bayonet Cap

With its familiar “push and twist” action, “bayonet cap” (also known as BC or B22d) is used on most regular light bulbs. It is 22mm diameter and with two locating lugs.

The “small b22 bayonet cap” (SBC or B15d) is very similar but only 15mm across.

Although generally used for mains voltage lamps, the SBC fitting can also be found in a very small number of specialist low voltage halogen lamps.

There are also many other “BC” variants including the 3-pin BC, B22d-3 Bayonet Cap sometimes used on Foreglow lamps but perhaps more commonly on High pressure mercury lamps for industrial applications. The BY22d is used on some low-pressure sodium (SOX) lamps.
