ANSI C 78.54:2019

The purpose is to standardize the Tubular LED (TLED) Lamp specification sheet, or data reporting format, as the means of communication of critical lamp characteristics such as:
a. Intended use ballasts (if applicable)
b. Reference circuit (if applicable)
c. Input voltage requirements (for use with mains voltage)
d. Other characteristics may include physical dimensions and/or temperature ratings for operation.
This Standard will cover all types of fluorescent replacement and retrofit TLED systems. This includes Ballast Driven (commonly referred to as Type A), Mains Voltage Driven (commonly referred to as Type B), External Driver Driven (commonly referred to as Type C), or hybrid type replacements. Lamps that do not fit existing replacement sockets, i.e., new lamp configurations, are not part of this Standard. Required contents and format of the specification sheet are provided. Manufacturers can include additional information.
