The National Electrical Manufacturers Association (NEMA) published ANSI C78.81-2014 American National Standard for Electric Lamps—Double-Capped Fluorescent Lamps—Dimensional and Electrical Characteristics
. In this updated version, eight datasheet revisions, four new datasheets, and additional information for high-frequency electronic ballast design are included.
ANSI C78.81 was developed by ANSI Accredited Standards Committee (ASC) C78. The standard establishes the physical and electrical characteristics of fluorescent lamps intended for application on conventional line frequency circuits and electronic high-frequency circuits. It should be noted that only double-based lamps of the regular linear shape are included.
