The Dark Side of LED Lighting

Return to Now

One of the world’s top photobiologists has been trying to warn the public for years about the dangers of the government-mandated phasing out of incandescent lighting.

While LEDs (light-emitting diodes) are up to 95 percent more energy efficient than incandescent bulbs, we are paying for that savings with our health.  

A physician and lecturer at Wismar University in Germany, Alexander Wunsch is an international consultant to governments, medical facilities and the lighting industry.

His message, though often ignored, is clear: blue light, isolated from all the other colors on the light spectrum, is damaging our retinas and disrupting our endocrine systems, resulting in all sorts of physical and mental illness.

It’s not a message the LED industry, governments looking to cut carbon emissions, or consumers saving money on electricity want to hear. But, as this Harvard Medical School report says, it is “backed up by study after study.”

Natural light vs. LED light

Natural light gives off all the colors (wavelengths) of the rainbow in a somewhat continuous manner, Wunsch explains in an interview with Dr. Mercola.

Typical “white” LED lights consist of a blue light-emitting diode and phosphor (fluorescent) coating.

    The only LED lights I have are flashlights since the bulb type are hard to find. All bulbs in the house are the incandescent bulbs. I also have a large stock on hand if needed. You can never have enough food, water, toilet paper , light bulbs and other items stashed away for an emergency. Yes I know light bulbs would be no good without electricity; however, they are in my pile of necessities. Have a Happy New Year.

    The new LED street lights are blinding in fog. The old orange sodium vapor lights were far better at lighting foggy or misty nights without blinding glare.
    Beside the health concern is the information that can and will be carried with the light. LiFi is the aim, total information saturation is the game! They’re going to make our illumination needs a part of the Internet of Things.
    Is there ANY part of life they don’t to spy on?

    I have them in my tool shop , there times when you need more lighting when your working . Now I can see stuff I have forgot about in the corners , I know there bad but I don’t live in my shop
