FULL CUTOFF PERFORMANCE
As the nations respected authority on lighting standards and
design recommendations, the IESNA, Illuminating Engineering
Society of North America defines four (4) unique luminaire
cutoff classifications to quantify the amount of light a
fixture directs upward toward the sky.
When specified with flat glass and a solid mid section, each
of the EPIC Collection’s horizontally lamped segmented
optical systems meets the strictest “Full Cutoff” classification
requirements, ensuring that zero measurable light is directed
upward from this luminaire.

FULL CUTOFF
Full cutoff and cutoff classified luminaires carry the endorsement of the
International Dark Sky Association (IDA) for their usefulness in limiting
the detrimental effects of sky glow, otherwise referred to as light pollution.
When faced with local or state adopted lighting ordinances, full cutoff
luminaires offer direct compliance in most all circumstances.
