LED street lights are rapidly being deployed across the globe. Lights, the Environment and Cancer When asking the question, Do LED lights cause cancer? Street lights are often mounted from high points, on poles. it is essential to understand many forms of cancer in terms of UV radiation and why we are at such increased risk from these harmful rays. Our LED street lights offer tool-less access for easy maintenance and easily replace outdated metal halide bulbs. BLUE LIGHT from LED street lights is linked to a ‘significant increase’ in the risk of breast and prostate cancer, new research has concluded. “The current street lights have round lenses, which allow a lot of stray light upward and to the sides,” Regina Wheeler, city public works director, wrote in an email. Exposure to the kind of blue light emitted by outdoor LEDs, smartphones and tablets may increase your risk of breast or prostate cancer, a new study suggests. These LED lights are a new one for me because I've not been surrounded by them before. The blue short-wavelength light emitted by superbright white light-emitting diode (LED) streetlights that help your neighborhood feel safe have been linked to an increase in colorectal cancer, according to new findings published in the journal Epidemiology by researchers at the Barcelona Institute for Global Health (ISGlobal). The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. A study led by the Barcelona Institute for Global Health (ISGlobal) and involving the University of Exeter found that participants living in large cities with heavy exposure to blue lights at night had double the risk of prostate cancer and 1.5 times higher risk of breast cancer. A white LED at CT 4000K or 5000K contains a high level of short-wavelength blue light; this has been the choice for a number of cities that have recently retrofitted their street lighting … They scare me t0o.

They provide the advantage of the long lifetimes (mean time to failure: >100,000 hours), reducing the number of field replacements and the costs associated with sending out a repair crew. Street lights are bright, effective lights designed to minimize glare and light large swatches of roadways, highways, and other streets. Research about the dangers they cause include doubling breast and prostrate cancer risks (I had breast cancer years ago) and the damage they cause the eyes.
