Rosslyn, Va.-based National Electrical Manufacturers Association (NEMA) has published LSD 11-2010, "White Paper on Outdoor Lighting Issues and Quality Lighting Applications." This white paper, last published in 2004, was produced by NEMA's Lighting Systems Division.

LSD 11 identifies specific lighting issues, defines correct lighting terminology, and provides straightforward technical guidance applicable to outdoor lighting installations in the United States. The publication is intended to be used by anyone dealing with the selection, installation, or management of outdoor lighting systems.

This revision includes updated information on existing regulations, top issues in the industry, and lighting technologies.

“A number of factors go into the process of selecting the right outdoor lighting for a particular application,” says Joseph Howley of GE Lighting, chair of the Lighting Systems Division. “Decision-makers address energy consumption, sky glow, visibility, safety and security, interaction with natural habitats, and other concerns. LSD 11 helps make sense of the many—and sometimes conflicting—guides and regulations on lighting.”
