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 | @ 90° | @ 80° |
Full Cutoff | 0 | 10% |
Cutoff | 2.5% | 10% |
5% | 20% |

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.

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.
