Arnold Wilkins, a professor of psychology at the University of Essex, said LED lights dim by 100 percent, which means the turn on and off hundreds of times every second. This constant flickering is not noticeable to many people, but Arnold said the effects of the flickering can include headaches, feelings of pain, and dizziness, according to a report by the Daily Mail (U.K.).The planet's health is more important than your own, you know...
Writing for The Conversation, Wilkins said, “We know from earlier work on fluorescent lighting that even though the flicker is too fast to be visible, it remains a likely health hazard. In 1989, my colleagues and I compared fluorescent lighting that flickered 100 times a second with lights that appeared the same but didn’t flicker. We found that office workers were half as likely on average to experience headaches under the non-flickering lights.”
“No similar study has yet been performed for LED lights,” Wilkins continued. “But because LED flickering is even more pronounced, with the light dimming by 100% rather than the roughly 35% of fluorescent lamps, there’s a chance that LEDs could be even more likely to cause headaches. At best, it’s likely to put some people off using LED bulbs because of the annoying, distracting effect of the flickering, which we know can be detected during saccades.”
