Concern Over LED Street Light Installation
The author has concerns about the methodology of installing LED streetlights. In the Havendale area, the old halogen lights were placed about 100 feet apart (one on each pole), giving a well-lit stretch for the entire length of the road. In this new dispensation, the new, brighter LED lights have now been placed on every […]

Impact of LEDs on Light Pollution
As infrastructure increases globally, artificial lighting is available in a larger and larger area. Developing countries chose LED lighting wrongly believing that LEDs are a long-term, more sustainable lighting solution. However, a huge problem with LEDs is their color. Making the switch from sodium lights that are orange-yellow in color, to the higher powered, bluish-white […]

Urban Lights Severly Infringe On Bird Migrations
This is exactly what the researchers found at the Tribute in Light. They measured more than 20 times the density of birds near the memorial than in surrounding areas. The birds spent long periods circling inside of the cone of illumination and they vocalized frequently. This meant that they were using precious energy, but not […]

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 […]

Woman in UK Complains LEDs Disturb Sleep
The American Medical Association, about one year ago, warned that circadian rhythm may be altered by LED streetlights above 3000 Degrees Kelvin Correlated Color Temperature (CCT). It is no wonder so many people are complaining that LED streetlights are disturbing their sleep. A UK woman is one of many inhabitants of plant earth that never even thought […]
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 […]
