Preface:

This is the harmonized ANCE, CSA Group, and UL standard for Self-Ballasted Lamps and Lamp Adapters. It is the third edition of NMX-J-578/1-ANCE, the third edition of CSA C22.2 No. 1993, and the fifth edition of UL 1993. This edition of CSA C22.2 No. 1993 supersedes the previous edition published in 2012. This harmonized standard has been jointly revised on March 26, 2021. For this purpose, CSA Group and UL are issuing revision pages dated March 26, 2021, and ANCE is issuing a new edition dated March 26, 2021.

This harmonized standard was prepared by the Association of Standardization and Certification (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Self-Ballasted Lamps, of the Council of the Harmonization of Electrotechnical Standards for the Nations of the Americas (CANENA), are gratefully acknowledged.

In Canada, for general information on the Standards of the Canadian Electrical Code, Part II, see the preface to CAN/CSA-C22.2 No. 0.

Scope:

1.1
These requirements are intended to cover both self-ballasted lamps and self-ballasted lamp adapters rated 120 to 347 V AC nominal for connection to screw-base, pin-base, or recessed single contact (RSC or R7) lampholders. These devices are intended for use in accordance with the National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical Code, Part I, CSA C22.1, in non-hazardous locations, and the Instalaciones Eléctricas (utilización), NOM-001-SEDE.

1.2
These devices incorporate resistance, reactance, or electronic (solid-state) type ballasts or power supplies. These devices employ various lamp technologies including, but not limited to, incandescent, fluorescent, high-intensity discharge lamps, light-emitting diodes.

1.3
These requirements also include Supplemental Requirements for Light-Emitting Diodes (LED), Supplement SA, for:
a) Self-contained LED lamps, rated 120 to 347 V AC nominal for connection to screw-, pinbase, and recessed single contact (RSC or R7) lampholders
b) Lamps for replacement of an ANSI standardized fluorescent lamp, and consisting of lightemitting-diode (LED) lamp technologies, with control circuitry, and a driver or power supply. The LED driver and control circuitry will be either integral with the lamp or remote from the lamp and
c) Component LED lamps, with or without control circuitry, an ANSI base other than bases mentioned in (a), for connection to LED driver having a low voltage output, such as replacement for tungsten-halogen, MR11 and MR16 shaped lamps.

1.4
This standard does not apply to medium-to-medium base (E26) fittings that incorporate controls such as photocells, motion detectors, radio controls, or dimmers covered by other standards.

1.5
These devices are not intended for use with emergency exit fixtures or emergency exit lights
