NEMA - ANSI C78.52
Electric Lamps - LED (Light Emitting Diode) Direct Replacement Lamps - Method of Designation
|Publication Date:||1 January 2017|
This standard describes a system for the designation of LED lamps that are direct replacements for existing ANSI standardized non-LED lamps. Lamps covered in this standard contain LED-based light sources. OLED lamps are not included at this time.
The purpose of the designation system covered by this standard is to provide an identification code for use in ANSI standards. Some lamp marking requirements are also identified. Guidance is given as to which characteristics are essential to assure interchangeability for safe operation and which characteristics affect performance.
The lamp characteristic data given by a manufacturer on an LED (Light-Emitting Diode) Direct Replacement Lamp Code Designation Request Form becomes the basis for the assignment of a designation. They have not been approved by the American National Standards Institute (ANSI) and do not constitute an American National Standard. Similarly, any consolidated listing of assigned designations with associated characteristics does not constitute an American National Standard.
