ANSI C136.14

Description / Abstract: This standard covers dimensional, maintenance and light distribution features that permit the interchange of enclosed side-mounted luminaires for horizontal-burning high-intensity discharge (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 with assurance that:

a) They will fit the bracket arm.

b) Pole strength requirements will not change.

c) Light distribution will be similar.

d) Similar maintenance procedures can be used.

Historically, luminaires covered by this standard are elliptical in shape with lenses that meet the requirements of ANSI C136.17. Luminaires other than HID may have a different unique shape as long as they meet the requirements listed above.

Excluded from this standard are luminaires having rectilinear and round shapes.
