The dangers of LED lamps

Flickering
Because LEDS are digital lights, they flicker. Most people cannot perceive that. This flickering is something that is very harmful to our biology," says Dr. Alexander Wunsch

Blue light
Researchers in France wrote that these factors "are the main causes of concern about the health risks of LEDs in terms of their toxicity to the eye and retina". They conducted a peer-reviewed animal study. After exposing rats to commercial white LEDs and four types of blue LEDs, they examined the animals' retinas. They found that the lights caused oxidative damage, injury and cell death to retinal cells and photoreceptor cells.

Toxins
LED lights do not contain mercury, but they do contain lead, arsenic and a number of other toxins and heavy metals.
