Lithonia Lighting - The best value in lighting
Nighttime Friendly designates products with superior optical control that are consistent with the goals of USGBC LEED® and meet Green Globes™ product criteria for light pollution reduction. These products are full cutoff and no more than 10% of the lumens from the luminaire are emitted above 80 degrees from nadir.
Increased emphasis on controlling stray light in outdoor applications is sending designers and communities in search of new lighting tools.  With full cutoff luminaires equipped with application specific optical systems, Lithonia Lighting can help you put the right amount of light in the right place.

Lithonia Lighting uses Nighttime Friendly™ to identify products that reduce negative impacts on the nighttime environment. Products designated with the Nighttime Friendly logo have no uplight, meet the IESNA definition for full cutoff optics and reduce high angle brightness. These measures of luminaire performance are consistent with sustainability standards for light pollution reduction.
