AMA Report Still Spawns Debate at Street and Area Lighting Conference
The LED Industry can’t overcome science offered by the American Medical Association (AMA). Over a year ago, the AMA published its report on hazards associated with LED streetlights. Industry proponents still insist that LED streetlights are safe. but Municipalities and Utility Companies are hedging. Link to Article PDF

3000K CCT Maybe a Sheep’s Cloak for LED Manufacturers
The American Medical Association’s (AMA) report of June 2016 has caused LED manufactures to tout the benefits of “warmer LEDs”. By recommending a maximum color temperature of 3000 Kelvin, the AMA may have opened the flood gate for LEDs to proliferate. The Lighting Research Center at Rensselaer Polytechnic Institute has cautioned that Correlated Color Temperature, as […]

DOE Continues to Rationalize use of LED Streetlights
The US Department of Energy continues to rationalize its promotion of LED Streetlights. The study offered up here states that “The findings in this document consequently represent only the contributions to sky glow from the street lighting system” and implies that LED Streetlights are not the primary source of “Sky Glow”. The study pits full power HPS […]

Read MoreIEEE Concludes LEDs are Viable Because of Flexibility
The Institute of Electrical and Electronic Engineers (IEEE) apparently embraces LED technology as acceptable in the long run because the technology is supposedly flexible. Engineers are often perceived as embracing technology for technology’s own sake, despite collateral effects. This article does not appear to deal with the true issue at hand – the amount of blue light emitted by […]
Read MoreAmerican Medical Association Warns LED Streetlights are Harmful
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”).

Read MoreFiltered White LEDs Help Preserve Dark Sky
Astronomers seek relief from light pollution caused by high-energy LED streetlights. Filtering shorter wavelength emissions from the LED streetlight spectrum is a tolerable, but not entirely acceptable compromise. Link to Article
Read MoreEarly Warnings About Blue-Light Hazards
Long before the American Medical Association announced its report warning of the hazards of blue-light and night, some reporters realized that blue-light should be avoided. This article was recently updated to include new data on installation of lower Correlated Color Temperature (CCT) LEDs in San Francisco. Link to Article
