Here are some symptoms your LED lights can cause. While the blue rays from LED lights improve alertness during the day, they pose problems, particularly at the end of the day, in the form of eye strain, migraines, and sleep disturbance. Harvard Health researchers say that blue light has a dark side, noting, “…environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health.” One of the reasons LED lights impact health, in particular migraine frequency, is the greater prevalence of blue light. “ Blue light has a dark side.” – Harvard Health Publishing Take a look at some symptoms you might not suspect stem from your LED bulbs. Both the spectral composition and temporal light modulation of LED bulbs affect our health. LED bulbs switch on and off hundreds of times per second in a strobe-like effect, which causes our eye movement to function improperly, causing a host of symptoms. Since LEDs can only be switched completely on or off, they flicker more prominently in order to simulate dimmer light. Fluorescent bulbs also use the flickering system, but it’s more harmful in LED lights when used with a dimmer. In addition, LEDs use a flickering technology that triggers eye strain and headaches. And as noted above, the color in LED bulbs is converted, so the color your eye perceives will not alert you to the prevalence of these more damaging color waves. Red and white LED lighting also trigger migraines. ![]() While a healthy dose of blue light like we receive from the sun has some benefits, long-term proximity to intense blue light from LED bulbs and screens has harmful effects.īut it’s not just blue light that’s to blame. Blue rays have shorter wavelengths and more energy than light waves of other colors. The prevalence of blue light waves in both LED and fluorescent bulbs exposes us to unnatural levels of light. ![]() ![]() In fact, a recent French study found LED lighting to be detrimental to the health of humans, as well as plants and animals. While LED lights are proposed as better for the environment, they use an unnatural technique that’s disturbing to the eye. LED Lights Aim to Protect Nature, But the Effect is Unnatural Increasing evidence suggests that LED’s advantages are outweighed by costly issues. And that “blue light” you’ve probably heard referenced in relation to screen usage can have a detrimental impact on our health. The “whiteness” of the bulb is determined by the amount of blue wavelengths it contains. While our eyes perceive LED light as white, it’s actually a blue, green, red, or amber light that’s converted to white. They are also cheap to manufacture and purchase, offering an energy and cost savings, at least at face value. LED bulbs currently maintain half of the market space in the lighting industry because they use only 20% of the energy of their incandescent counterparts. LED stands for “ light emitting diodes,” an electrical advance that is popular for energy efficiency superior to incandescent and fluorescent bulbs. What is LED Lighting and Why is It So Prevalent?
