How LED Lighting May Compromise Your Health

How LED Lighting May Compromise Your Health | Cool Future Technologies | Scoop.it
From articles.mercola.com - October 27, 2016 1:24 PM

In this interview, Dr. Wunsch, a world class expert on photobiology, shares the hidden dangers of LED lighting that most people are completely unaware of. 

 

  • Near-infrared is important as it primes the cells in your retina for repair and regeneration, which explains why LEDs — which is devoid of infrared — are so harmful for your eyes and health 

  • One-third of the energy your body consumes comes from the food you eat. The vast majority of the energy your body needs to maintain the systemic equilibrium comes from environmental infrared light exposure

  • LEDs sabotage health and promote blindness. Limit your exposure to blue light during the daytime and at night. Swap out LEDs for incandescents or low-voltage incandescent halogen lights
Sepp Hasslberger's insight:

LED lights are the future ... or so it might seem. But it turns out that they leave out an important part of the spectrum that we need for good health. Mercola has an excellent artile, with video interview, on the lighting issue.

Sepp Hasslberger's curator insight, October 27, 2016 1:21 PM

A very interesting article by Dr Mercola on lighting. It explains the differences between incandescent lights, including halogen and LED lights. Apparently LEDs leave out an important part of the spectrum that is healing for the human organism...

Return of incandescent light bulbs as MIT makes them more efficient than LEDs 

Return of incandescent light bulbs as MIT makes them more efficient than LEDs  | Cool Future Technologies | Scoop.it
From www.sott.net - June 4, 2016 2:17 PM

Ever since the EU restricted sales of traditional incandescent light bulbs, homeowners have complained about the shortcomings of their energy-efficient replacements. 

The clinical white beam of LEDs and frustrating time-delay of 'green' lighting has left many hankering after the instant, bright warm glow of traditional filament bulbs. 

But now scientists in the US believe they have come up with a solution which could see a reprieve for incandescent bulbs. 

Researchers at MIT have shown that by surrounding the filament with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through. 

They refer to the technique as 'recycling light' because the energy which would usually escape into the air is redirected back to the filament where it can create new light. 

"It recycles the energy that would otherwise be wasted," said Professor Marin Soljacic.

Sepp Hasslberger's insight:

This is still deep in research - super efficient incandescent bulbs, their light and efficiency better than both neon and LED.
