PSG11 782 LITHONIA LIGHTING OUTDOOR www.lithonia.com PRODUCT INFORMATION NIGHTTIME FRIENDLY Nighttime Friendly Lighting Notes 1 May not meet Nighttime Friendly standards with HS option. 2 Will not meet Nighttime Friendly standards with DL or EHS options. Lithonia Lighting is a leader in providing a variety of outdoor luminaires devoted to energy and environmental concerns. Many communities are interested in maintaining nighttime visibility, safety and security while preserving the night sky. Quality outdoor lighting considers the visual needs of the application while reducing glare and light trespass onto neighboring properties, therefore minimizing sky glow and overall energy usage. Listed below are several Lithonia Lighting product families that include a wide range of cutoff and full-cutoffluminaires that produce quality lighting and minimize night sky glow. The Illuminating Engineering Society of North America (IESNA, or IES) provides classifications for luminaires according to their glare control and high-angle brightness. These classifications, along with their benefits and limitations, are described in the Technical and Design Considerations section on pages 1104-1105. Acuity Brands 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. For applications where there is a concern with light trespass on neighboring properties, consider products that limit light behind the pole, such as the Type 4 sharp cutoffoptical system or house-side shielding.

SR4SC Spill light or light trespass is the light that illuminates surfaces beyond the property line. An example is the light on a bedroom wall coming through the window from the ball field across the street. A number of ordinances place limits on spill light near the property line as the sole means of controlling light trespass. The most effective way to minimize spill light from a location is to apply for- ward throw optics around the perimeter. Lithonia Lighting's optic is designed specifically for this application.
