Description / Abstract:
This standard is intended to cover 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.
It is not intended that compliance with this standard will
permit interchangeability with existing roadway equipment without
thorough engineering review and evaluation.
Structural requirements for poles and brackets shall be
evaluated with respect to both strength and vibration. Vibration
dampers may be required.
Where specified, architectural luminaires of similar effective
projected area and weight meeting the requirements of this standard
based on appropriate engineering review and evaluation may be used
in roadway applications with the assurance that:
a) They will fit the standard roadway mounting devices and
methods
b) Light distribution patterns and photometric data available
from manufacturers will be consistent with standard roadway
luminaires as specified in IES standards.
c) Physical, operational, and maintenance characteristics will
be similar to standard roadway luminaires.
