Counting the Blues in Outdoor Lighting

Natural systems are particularly sensitive to wavelengths in the blue portion of the spectrum, and as a result concerns are being increasingly raised about the potential for negative effects of blue wavelengths emitted by artificial light sources. However, these concerns are often expressed without specifying the metrics for evaluating blue content and also lack consideration of other important characteristics that contribute to the end result, such as light intensity, length of exposure, time of day, and wavelength. To improve understanding of these more complex system interactions, the U.S. Department of Energy is supporting investigations to better quantify the emission characteristics of lighting technologies used around the country.  This presentation describes a few initial efforts and the methodologies currently pursued.
