The National Electrical Manufacturers Association (NEMA) published ANSI C136.23-2012 American National Standard for Roadway and Area Lighting Equipment—Enclosed Architectural Luminaires.
ANSI C136.23-2012 covers physical, operating, maintenance, and light distribution features that permit use of architectural luminaires in roadway applications when so specified. The architectural luminaires covered by this standard include side-mounted, square, rectangular, cylindrical, spherical, and other types of decorative or nostalgic historical style luminaires that are considered to be any significant deviation from the luminaire style that has evolved in the industry as predominantly (commonly) known as the “cobra head” style covered in ANSI C136.14.
This standard was updated to reflect current industry practices and to realign with other C136 standards.
