The National Electrical Manufacturers Association (NEMA), Rosslyn, Va., introduced its new American National Standard for Roadway and Area Lighting Equipment—Elliptically Shaped, Enclosed Side-mounted Luminaires (ANSI C136.14-2014).
This standard, which will be of interest to manufacturers and installers of roadway and area lighting, as well as municipalities and utilities, includes added requirements for light sources other than high-intensity discharge (HID), updated references, updated language to reflect committee preference, and added requirements for ingress protection.
The standard covers dimensional, maintenance, and light distribution features that permit the interchange of enclosed, side-mounted luminaires for horizontal-burning HID lamps and other light sources used in roadway and area lighting equipment. This type of luminaire has traditionally been used for street or roadway lighting, and has commonly been referred to as “cobrahead” style luminaires.
Luminaires of similar size, shape, and weight meeting the requirements of this standard may be used interchangeably within a system as long as they will fit the bracket arm, don’t change pole strength requirements, provide similar light distribution and require similar maintenance procedures.
