NightSky^® Optical Systems

A light distribution where there is zero candela at or above 90 degrees vertical from nadir and where the candela value does not exceed 10% of the maximum intensity at or above a vertical angle of 80 degrees. This applies to all symmetrical angles around the luminaire.

A thousand points of light reflected downward to protect the night sky. This is an enlargement of our new Star-Shield^® ROH5-L optical system showing the design and detail. The segmented reflector is made of highly specular aluminum to achieve the reflective surface
