Listed below are several product families that include a wide range of cutoffand full-cutoffluminaires that produce quality lighting and minimize night sky glow. IESNA The Illuminating Engineering Society of North America provides a variety of reference material on effective outdoor lighting design. Both the IESNA Lighting Handbook, 9th edition, and Recom- mended Practice No. 33 (RP-33-99), Lighting for Exterior Environments, offer discussions on design practices and suggested spill light limitations. WFL NEMA The Luminaire Section of the National Electrical Manufacturers Association published a document entitled "White Paper on Outdoor Lighting Code Issues". This paper highlights the pros and cons of methods to control light trespass. The NEMA Statement of Principles on Outdoor Lighting Codes also provides general guidance in the establishment of local lighting ordinances. IDA The International Dark-Sky Association is a grassroots organization that promotes quality outdoor lighting practices. Of particular interest to IDA is the reduction of sky glow. Their guidelines are of significant benefit for lighting installations near astronomical observatories or intrinsically dark areas such as national parks.
