The National Electrical Manufacturers Association (NEMA) published ANSI C136.53-2017 American National Standard for Roadway and Area Lighting Equipment—Enclosed Pendant Mounted Luminaires. Developed by the ANSI Committee for Outdoor Lighting, this new standard for roadway lighting covers dimensional, maintenance, and light distribution features that are interchangeable in enclosed pendant-mounted luminaires.

Luminaires of similar size, shape, and weight meeting the requirements of this standard may be used interchangeably within a system with the assurance that:

-They will fit the mounting pendant

-Pole strength requirements will not change

-Light distribution will be similar

-Similar maintenance procedures can be used

"This standard includes features that permit the interchange of enclosed pendant-mounted luminaires whose center mass is directly below the mounting bracket," said Kevin Fitzmaurice, Chair of the ANSI C136 Committee.  

ANSI C136.53-2017 is available in hard copy or as an electronic download for $40 on the NEMA website. 

The ANSI Accredited Standards Committee (ASC) C136 for Roadway and Area Lighting Equipment is currently seeking interested members, particularly in the underrepresented categories of End User and General Interest.
