A Small Bayonet Cap (SBC) is a type of lamp cap or base used for many small light bulbs, primarily in the United Kingdom. It's characterized by a small, push-and-twist mechanism for securing the bulb in the socket. The SBC is distinguished by its two small pins on the base, which fit into matching slots in the socket. SBC bulbs are commonly found in various applications, from table lamps to chandeliers, and they are available in different shapes, sizes, and wattages. The SBC design ensures a secure connection and is an important part of the British lighting standard, providing a reliable and safe way to light up homes and commercial spaces.
