1. Screw Fittings
Screw fittings, also known as Edison screw fittings, are one of the most common types of light bulb fittings. They are named after Thomas Edison, the inventor of the first commercially viable light bulb. These fittings come in two sizes: E27 (large) and E14 (small). The E27 fitting is used for larger bulbs, while the E14 fitting is used for smaller bulbs. Screw fittings are easy to install and can be found in a wide range of light bulb types, including incandescent, LED, and compact fluorescent bulbs.

2. Bayonet Fittings
Bayonet fittings are another popular type of light bulb fitting. They are named after the bayonet mount used in firearms and consist of two pins that are pushed into slots on the light bulb socket. Bayonet fittings are available in two sizes: B22 (large) and B15 (small). The B22 fitting is commonly used in ceiling lights and table lamps, while the B15 fitting is used in smaller lamps and appliances. Bayonet fittings are secure and easy to install, making them a popular choice among homeowners.

3. Pin Fittings
Pin fittings are typically used in fluorescent and halogen light bulbs. They consist of two or more metal pins that are inserted into the socket and twisted to secure the bulb in place. Pin fittings are available in various configurations, including 2-pin, 4-pin, and bi-pin. The type of pin fitting you need will depend on the specific light bulb you are using. Pin fittings are commonly found in recessed lighting fixtures and track lighting systems.
