Scope

1.1 This Standard specifies photometric performance requirements for luminaires that are used for roadway and street lighting applications as a function of unit power density (UPD).

1.2 The following light sources are addressed in this Standard:
a) clear HPS lamp
b) clear metal halide lamp and
c) LED.

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) relative photometry for HID sources as per ANSI/IES LM-63 and IES LM-31
e) luminaire input power in watts and rated luminaire lumens for LED sources and does not include constant light output (CLO) applications; and
f) 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, based upon typical roadway configuration.
Tables 4, 5, and 6 are intended to be used to establish maximum UPD values for typical applications as per the parameters listed in Table 1. UPD values provided in this Standard are not intended for specification or application purposes.
User specific road geometries could differ from the templates used in the creation of these Tables. Requirements of specific designs might necessitate different variations in distribution, lumen packages, and wattages. Users should review UPD as a measure of comparison across suppliers, within their own geometry, and should note that UPD levels will then vary from the Tables within this Standard.
