What size is a regular bulb socket?
A regular bulb socket, also known as an Edison screw base or E26/E27 socket, is a common type of light bulb socket used in residential and commercial lighting fixtures. The size of a regular bulb socket refers to the diameter of the threaded base that the light bulb screws into.
What is the Size of a Regular Bulb Socket?
The standard size for a regular bulb socket is 26 millimeters (mm) in diameter, which is equivalent to 1 inch. This size is also known as an E26 socket. In some regions, such as Europe, the slightly larger E27 socket, which is 27 mm in diameter, is also considered a regular bulb socket size.
Why Does Bulb Socket Size Matter?
The size of the bulb socket is important because it determines the type of light bulb that can be safely used in a fixture. Using a bulb with the wrong base size can be a fire hazard, as the bulb may not fit properly or could become loose in the socket. It's crucial to match the bulb base size to the socket size to ensure a secure and safe connection.
