2005-2006 Light Pollution Study
WHAT YOU GET

“Light pollution” primarily deals with three outdoor lighting issues—sky glow, light trespass and glare. Addressing light pollution has grown in significance as an industry trend due to greater awareness of the issues, LEED, changes in codes, and the proliferation of anti-light pollution laws across the country at the state and local level.

How aware are lighting designers, architects and engineers about light pollution issues? How important are various aspects of light pollution in their decision-making? Who is most influential about making outdoor lighting decisions that address light pollution? What motivates them the most to address light pollution? What strategies and product types are most popular to deal with light pollution? What is their response to outdoor lighting manufacturer product and service offerings? What kinds of laws are they encountering, and how easy are they to understand and implement? And what are the most significant roadblocks to properly addressing light pollution?

The 2005-2006 Light Pollution Study was developed to achieve two purposes. First, it is intended to help outdoor lighting manufacturers to develop a deeper understanding of designer, architect and engineer attitudes towards light pollution issues. Using this information, manufacturers may develop products, programs and approaches that reflect a deeper understanding of the market. Second, the Study is intended to help municipalities, code writers and other organizations develop practical, easy-to-understand, and easy-to-implement codes and legislation that reflect input from lighting professionals.

The 2005-2006 Light Pollution Study contains more than 100 pages of data tables, graphs, verbatims and analysis based on a survey to 2,847 North American architects, lighting designers and engineers, with a 6.9% response. The study breaks down the response by specifier group, making this three studies in one with direct comparisons and contrasts between each group.
