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.
ALLOWABLE CANDELA
Full Cutoff
Cutoff
Semi-Cutoff
Non-Cutoff
In downlight only applications, each of the available
ENTRI Series optical systems meets the strictest "Full Cutoff"
classification requirements, insuring that zero measurable
light is directed upward from the luminaire.

ENTRI Series presents an attractive alterative
to traditional refractive based non-cutoff wall
pack luminaires, which generate considerable
amounts of glare while providing a less
90° appealing form.

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.
