The Scientific Reason You Don’t Like LED Bulbs — and the Simple Way to Fix Them

Scientists studying the flickering light of LED bulbs suspect the movements may cause headaches in some people, The Conversation reports. Since you may not be aware that the light is actually flickering, this may explain why some people report not liking LED lights even though they don’t know why they feel that way. To assure LED lights are used, researchers suggested consumers make sure these lights meet industry standards, which require that the flickering be kept at imperceptible levels.  

When it comes to industry standards, even if the bulbs you buy do meet the standards, LED lighting may be compromising your health in a number of ways you’re unaware of. Quite bluntly, LEDs sabotage your health and promote blindness — and this is vitally important to know as there's been a major transition to using LED as a primary indoor light source. 

LED lighting also may actually be one of the most important, non-native EMF radiation exposures you're exposed to on a daily basis. If you chose to ignore these new insights, it can have very serious long-term ramifications, such as age-related macular degeneration, which is the leading cause of blindness in the United States and elsewhere.

When buying LEDs, look at the color rendering index (CRI) of the bulbs. Sunlight is the gold standard and has a CRI of 100. So do incandescent light bulbs and candles. What you're looking for is a light that has an R9 (full red spectrum) CRI of about 97, which is the closest you'll ever get to a natural light with an LED. Another concern is your LED-backlit computer screen, so make sure you turn off all your electronic devices at least an hour before you go to bed.
