This Technical Memorandum defines a classification
system for outdoor luminaires that provides information
to lighting professionals regarding the lumen
distribution within solid angles of specific interest.
The lumens within these solid angles are intended to
be one of the metrics used to evaluate luminaire
optical distribution including the potential for light
pollution and obtrusive light, but not as the only metric
that should be evaluated. Light pollution and
obtrusive light result not only from the optical characteristics
of the luminaires, but also from the application
of those luminaires within an outdoor site or
roadway. A detailed evaluation of the lighting performance
for the outdoor site should be based not only
on the luminaire optics, but also on overall system
design, including luminaire locations, utilization of
light where it is needed, lighting quality, visual tasks,
aesthetics, safety requirements, and security issues.
