NEMA - ANSI C78.55
Electric Lamps — LED Lamp Specification Sheets for HID Replacement and Retrofit Applications
|Publication Date:||1 January 2020|
The purpose is to standardize LED Lamp specification sheets for HID Replacement and Retrofit Applications, as the means of communication of critical lamp characteristics such as:
a. Intended use ballasts (if applicable)
b. Reference circuit (if applicable)
c. Identify input voltage requirements (for use with mains voltage)
d. Light Distribution
e. Other characteristics-may include physical dimensions and/or temperature ratings for operation.
This Standard will cover all types of HID replacement and retrofit applications using LED lamps. The minimum contents and format of the specification sheet will be provided. Manufacturers can include additional information.
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.
