New Lighting Standard Offers Performance Specifications for LED Lamps

ROSSLYN, Va., December 19, 2019—The National Electrical Manufacturers Association (NEMA) published ANSI C78.53-2019 American National Standard for Electric Lamps— Performance Specifications for Direct Replacement LED (Light Emitting Diode) Lamps. This new Standard describes the electrical, mechanical, and photometric characteristics of LED lamps that are direct replacements for existing ANSI standardized non-LED lamps.

“This important new Standard identifies key characteristics of direct replacement LED lamps that should be available to consumers and application specialists. It covers general direct replacement LED lamps and specific requirements for direct replacement LED lamps used in tubular fluorescent and high-intensity discharge (HID) ballasted systems,” said Andrew Jackson, manager, Lighting Test Center Americas Signify North America Corporation, and chair of the ANSI Electric Lamp Committee. “This Standard provides information to help manufacturers better select and compare products for specific applications, limiting confusion about LED direct replacement lamp performance in existing luminaires and systems.”

The primary audience for this Standard is manufacturers of LED electric lamps.

ANSI C78.53-2019 is available for $79 in hard copy and electronic download on the NEMA website.

The NEMA Lighting Systems Division, as the secretariat of ANSI ASC C78, Lamps, is looking for industry experts specifically in the underrepresented categories of “Users” and “General Interest” to participate in Standards development activities. Please contact NEMA at if you are interested and indicate your interest category and area of expertise.
