lamp holder accessories

“medium” indicates a lamp holder that is about 1″ in diameter. Synonyms for medium are “standard”, “Edison” and E26. It’s best to call medium “medium” or “E26” because when other bases are being discussed, the two other synonyms may cause confusion.

Here in the US and elsewhere, there are other screw-thread lamp holder accessories that are prefixed with an “E” followed by a number indicating diameter expressed in millimeters. “Edison” is medium in the US.

Dimensions and tolerances for screw bases are standardized in ANSI standard C81.67 and IEC standard 60061-1. The two standards have mostly been harmonized, although several types exist in only one of the two standards with no equivalent in the other.The designation refers to the diameter in millimeters.
