Stop the use of harmful blue-rich lights in Pasadena, CA

The City of Pasadena, CA is installing new street lights that are known to have detrimental effects on human health. These lights are excessively bright and emit what is known as blue-rich light which causes glare, pain and damage to the eye, and suppresses melatonin at five times the rate of previous lighting methods. They also have detrimental effects on wildlife such as migratory birds.

The American Medical Association issued a unanimous statement last summer advising that new lights be properly shielded to reduce glare and operate at color temperatures of less than 3,000K (producing a warmer, gentler light).

I have a simple app on my phone that shows the new street lights are far in excess of these limits set by the nation’s physicians. In addition, many commercial properties, such as the Popeye’s on Lake at Mountain, have installed their own LED panel lighting systems that are far worse than the city’s new lights.

The residents of Davis and Monterey in California have already successfully sued their municipalities to change blue-rich street lighting, costing tens of thousands of dollars.

The Chicago Astronomical Society is petitioning the city of Chicago against the use of LED technology saying, “It’s important that we do NOT use bright white/ blue-rich spectrum lighting as it has serious negative effects on human health, the environment, and the ecosystem.”

Given all that is known about the health effects of blue-rich light and people’s response to it, it would be wise for the city of Pasadena to change course before replacing anymore lights.

This petition calls on the City of Pasadena to eliminate the use of blue-rich light in all municipal, commercial and private outdoor applications using the guidelines set forth by the American Medical Association and choose 2,200K or warmer for the city's new streetlights*.

*The science on LED's is evolving daily. The request for 2,200K or warmer streetlights was added on 11/18/2018 when the petition already had 250 signatures.
