FULL CUTOFF PERFORMANCE
As the Nations respected authority on lighting standards and
design recommendations, the IESNA, Illuminating Engineering
Society of North America defines four unique luminaire
cutoff classifications to quantify the amount of light a
fixture directs upward toward the sky.
Each of the available VISION Site optical systems meets the
strictest "Full Cutoff" classification requirements, ensuring
that zero measurable light is directed upward from the
luminaire.

FULL CUTOFF
Full cutoff 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.
