How to Designate LED Direct Replacement Lamps

05/30/2017 |

ANSI C78.52 is a new lighting standard on how to designate LED lamps that are direct replacements for existing lights

ANSI Accredited Standards Committee C78, Electric Lamps, published ANSI C78.52-2017 American National Standard for Electric Lamps—LED (Light Emitting Diode) Direct Replacement Lamps—Method of Designation. The National Electrical Manufacturers Association (NEMA) serves as secretariat for the standard. 

The new lighting standard helps FMs figure out how to designate LED lamps that are direct replacements for existing, ANSI-standardized, non-LED lamps. Lamps covered in this standard contain LED-based light sources. This form allows a manufacturer to request a direct replacement designation using lamp characteristic data. 


“This new standard also provides an LED Direct Replacement Lamp Code Designation Request Form,” says Andrew Jackson, Manager, Corporate Regulatory & Certification Laboratory, Chair of the ANSI C78 Committee.

ANSI C78.52-2017 is available for purchase for $350 in hard copy or as an electronic download on the NEMA webpage.
