1 Scope

1.1
This Standard specifies photometric performance requirements for luminaires that are used for roadway and street lighting applications.

1.2
The following light sources are addressed in this Standard:
a) clear HPS lamp;
b) clear metal halide lamp;
c) induction; and
d) LED.
Note: Future editions of this Standard might include other light sources, such as plasma.

1.3
This Standard is based on
a) average luminance, luminance uniformity ratio, and veiling luminance ratio as defined in ANSI/IES RP-8;
b) nominal input power in watts for HID sources;
c) rated lamp lumens for HID sources;
d) luminaire input power in watts and rated luminaire lumens for Induction and LED sources; and
e) absolute photometry for LED sources as per IES LM 79.

1.4
This Standard is not a design document, and is intended to establish luminaire photometric performance efficiency only.
