A B22 smart bulb is a type of light bulb that uses the B22 socket, which is commonly used in the UK and other countries. It is a bayonet-type socket that is typically used in ceiling fixtures and lamps. B22 smart bulbs are compatible with smart home systems and can be controlled using a smartphone app or voice commands. They can change colours, brightness, and temperature, and can be scheduled to turn on and off automatically.
