What is Medium Base Bulb
A medium base bulb, also known as an E26 socket, is a standard light bulb commonly used in residential settings. It is characterized by its threaded brass base, which is referred to as the medium base. This type of base is the most widely used and commonly found in lamps and fixtures. The medium base bulb is typically found on A19, A15, and A21 lamps, which are commonly used in table lamps and residential ceiling fixtures. It is important to note that the medium base is the most common type of base used on both incandescent and LED lamps.
Compared to other types of bases used in lighting, such as the intermediate base, candelabra base, mini-candelabra base, and mogul base, the medium base is larger than the intermediate base, candelabra base, and mini-candelabra base, but smaller than the rarer mogul base. However, adaptors are available to fit a smaller base into a larger socket, allowing for flexibility in lighting options. It is worth mentioning that the names of the sockets correspond to the names of the bases.
