The National Electrical Manufacturers Association (NEMA) has recently published two new standards for Roadways and Area Lighting Equipment. The first is ANSI C136.16-2014 American National Standard for Roadway and Area Lighting Equipment—Enclosed, Post Top-mounted Luminaires. This standard is useful to roadway and area lighting manufacturers, municipalities, and utilities; and provides requirements to allow for the interchangeability of enclosed, post top-mounted luminaires.

ANSI C136.16 was developed by ANSI Accredited Standards Committee (ASC) 136. It covers dimensional, maintenance, and light distribution features that permit the interchange of enclosed, post top-mounted high-intensity discharge lamps, solid-state light sources (i.e., light-emitting diode), compact fluorescent lamps, and induction luminaires whose center of mass is approximately over the mounting tenon.

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

• they will fit the mounting tenon,
• pole strength requirements will not change,
• light distribution will be similar, and
• similar maintenance procedures can be used.

Another new standard is the ANSI C136.34-2014 American National Standard for Roadway and Area Lighting Equipment—Vandal Shields for Roadway and Area Lighting Luminaires. This standard is useful to roadway and area lighting manufacturers, municipalities, and utilities.

ANSI C136.34 was developed by ANSI Accredited Standards Committee (ASC) 136, and covers supplementary vandal shields used to protect luminaires and luminaire accessories used for roadway and area lighting. Revisions to this version include updated references, added section titles, and revised language to be consistent with other C136 standards.

ANSI C136.34-2014 may be downloaded or purchased in hard copy for $52 on theNEMA website, while the ANSI C136.16-2014 may be downloaded or purchased in hard copy for $38 on the NEMA website.
