CCT Not Useful for Selecting LED Streetlights
Rensselaer Polytechnic Institute’s Lighting Research Center (LRC) chimed in with respect to the American Medical Association’s recommendation to use Correlated Color Temperature (CCT) as a metric for selecting LED streetlights. According to the LRC, CCT does not tell the whole story. To predict the harm caused by LED streetlights, it is important to consider the […]

The American Medical Association (AMA) now warns that the blue-rich, white light from LED streetlights is harmful to people and animals alike. The AMA recommends that LED Streetlights with lower Correlated Color Temperature (CCT) be used instead of the more efficient 4000K fixtures. CCT is measured in degrees Kelvin (“K”).

According to the American Medical Association (AMA), “The first is discomfort and glare. Because LED light is so concentrated and has high blue content, it can cause severe glare, resulting in pupillary constriction in the eyes. Blue light scatters more in the human eye than the longer wavelengths of yellow and red, and sufficient levels […]

New Map Shows the Dark Side of Artificial Light at Night
The greatest value of this study from Falchi and his colleagues may be the baselines it sets for policy debates about light pollution and any associated changes in the level of nighttime illumination. The atlas’s finding about the pernicious skyglow effects of blue-white LEDs, Longcore says, “is a message that incentivizing conversion to cheap blue-white […]
Read MoreLED Streetlight v. Wildlife
According to this article, LED streetlights also have an adverse effect on nocturnal wildlife. Scientists have found that migrating birds are attracted to unnatural lighting, which often results in injuries or death when they collide with reflections on buildings or other structures. High-intensity light pollution has also been linked to low survival rates for hatchling […]
