“There is no evidence of direct adverse effects from LED emissions in normal use Thus their conclusion misleadingly reads: SCHEER’s attention to an artificially limited segment of society. However, that meant it became necessary to narrow Permit the continued proliferation of LEDs. The transition to LEDs wasĪlready well underway, creating pressure and momentum to reach a favorable finding, one that would Risks) to review recent evidence to assess human health risks from LEDs. In 2018, still focusing on efficiency and with a motivation to ban incandescent bulbs, TheĮuropean Union asked SCHEER (The Scientific Committee on Health and Environmental Emerging What the lighting industry did know was that LED exposure was capable of wreakingīiological, neurological and endo-chronological havoc. Mention that high-risk, human, LED-susceptibility tests can’t be conducted because of danger to the The lighting industryĮmphasized the lack of specific laboratory evidence on LEDs’ human health impacts, neglecting to Was mostly unaware – and the industry barely mentioned – the breadth and variety of potential damageįrom LED exposure to living things of all kinds.Įngineering research has different goals than medical research. Schools, medical facilities, outdoors and in public light fixtures without further examination. Savings and branding LEDs as ‘green,’ LEDS began suddenly turning up in consumer products, offices, Side-stepping toxic effects, emphasizing energy Incandescent bulbs and focused on LEDs instead. Specialized technology, not expected to move out of the laser category and into regular use.īy the mid-2000s, however, the industry turned away from promising work on super-efficient The lighting industry has also known for decades that LEDs cause toxic effects. Here’s some background on how – despite this foreknowledge – LEDsĬame to be installed where they’re exposing everyone and everything, just about everywhere: These references are recent, but the probability that LEDs caused harm to living organisms was Should lead to “more research on an urgent basis so that potentially harmful lighting may be A 2018 paper entitled “Blue Light and Fruit Flies: A Warning for Humans” (Journal of AgingĪnd Mechanisms of Disease) describes LED exposure causing reduction in lifespan, retinalĭamage, brain degeneration and aging due to stress. Boy babies are more vulnerable than girls. LED street lights impacted yet-to-be-born babies, causing reduced birth weight, shortened A 2018 real world study (as opposed to lab results) found that increased skyglow in cities with The “ blue LED-exposed zebra fish all died A 2019 study on zebra fish revealed that LED lighting affected morphology, locomotorĪctivities, mortality and hatching rates, oxidant and anti-oxidant parameters and geneĮxpressions related with melatonin circulation. The number of embryonic nuclei withįragmented DNA was significantly higher in embryos treated with white light. With the embryonic implantation capacity in mice. A 2019 experiment with mouse embryos demonstrated how short wave LED light interferes Resulting human implications are often alarming: Studies are conducted on species selected for commonalities with human biology. Participating in experiments involving potential seizure-inducing lights including LEDs). (Epilepsy, for example, precludes someone from Human test subjects identified as high-risk. Medical researchers conduct animal studies because medical ethics largely prohibit using HumansĪnd wildlife have few defenses against it. Light which is biologically disruptive and wholly unfamiliar to natural systems. LEDs emit short-wave, white/blue, directional, non-uniform, hyperpenetrating Unlike older style bulbs, properties inherent to LEDs make this light The National Library of Medicine has numerous research articles showing profound adverseĮffects from LED light exposure. Light Emitting Diodes have been shown to cause epileptic seizures.
