ANSI C78.81 sets forth the physical and electrical characteristics of the principal types of fluorescent lamps intended for application on conventional line frequency circuits and electronic high-frequency circuits. The National Electrical Manufacturers Association (NEMA) announced that ANSI Accredited Standards Committee C78 revised ANSI C78.81-2016 American National Standard for Electric Lamps—Double-Capped Fluorescent Lamps—Dimensional and Electrical Characteristics. Specifications for the lamp itself and the interactive features of the lamp and ballast are given. Only double-based lamps of the regular linear shape are included.

This revision added a T5 Method of Measurement reference for clarity and many data sheet numbers were corrected High frequency (HF) programmed-start open circuit starting voltages also were added for the various T8 data sheets containing HF requirements.

NEMA’s Lighting Systems Division, as secretariat of ANSI’s ASC C78 for Electric Lamps, is looking for industry experts in the User and General Interest categories to participate in standards development activities. Contact NEMA at nemalighting@nema.org if you are interested. Please indicate your interest category and your area of expertise.

ANSI C78.81-2016 is available in hard copy or as an electronic download for $500 on the NEMA website.
