Analog Versus Digital Lighting
LED lamps are a form of digital non-thermal lighting whereas incandescent light bulbs and halogens are analog thermal light sources.
- “For a color changing system you have three different LEDs, a red, a green and a blue LED, and the intensity of these three colored channels has to be changed in order to achieve different color use, which is perceived by the eye in the end. The control of the intensity output of an LED is realized in a digital manner because it’s very difficult to have a low intensity in many different steps.
- The dimming of LEDs is realized by a so-called pulse-width modulation, which means the LEDs switch on to the full intensity and then they fully switch off, and then they switch on again. So we have the constant on and off in frequencies, which are higher than our eyes are able to discriminate. But on the cellular level, it is still perceivable for the cells …
- [T]his causes a flicker, which is not perceivable for let’s say 90 percent of the population. But it’s still biologically active. And flicker is something that is very harmful to your [biology].”
You’ve likely experienced this if you’re old enough to recall the older TVs that had a very visible and intense flicker. Modern flat screens do not have this perceptible flicker, but they’re still switching on and off. Scientists are now trying to develop systems capable of transmitting information via high-frequency flicker in the LED lighting to replace the wireless LAN system. According to Wunsch, this is a very bad idea, from a health perspective.
- “I call these LEDs Trojan horses because they appear so practical to us. They appear to have so many advantages. They save energy; are solid state and very robust,. So we invited them into our homes. But we are not aware that they have many stealth health-robbing properties, which are harmful to your biology, harmful to your mental health, harmful to your retinal health, and also harmful to your hormonal or endocrine health,” he says.
Unfortunately, the use of LEDs has been mandated by federal policy in both the U.S. and much of Europe, in an attempt to conserve energy. While inarguably effective in that regard, the biological impact of these bulbs has been completely ignored, and by mandating them, options have been restricted.
Adenosine Triphosphate (ATP) – is vital to the human body to function
The mitochondria of each cell in the human body produce almost one’s entire bodyweight in adenosine triphosphate (ATP) per day (!) and the human body can only live for 15 seconds without it, as compared to 4-10 minutes without air, 3-4 days without water. Another shocking thing we learn is that we only receive 1/3rd of what is converted into ATP from the food we eat. The overwhelming percentage of our ATP production comes from the light we receive through our eyes and skin.
In an early study conducted by Ham, Ruffolo, Mueller and Guerry, (1980) rhesus monkeys were exposed to high‑intensity blue light at 441nm for a duration of 1000 seconds. Two days later lesions were formed in the retinal pigmented epithelium (RPE.) These lesions consisted of an “inflammatory reaction accompanied with clumping of melanosomes and some macrophage invasion with engulfment of melanosomes which produce hypopigmentation of the RPE” (Ham et al., 1980, p.1110). Since melanin, a common pigment component present in the RPE, strongly absorbs blue light, there is reason to be concerned that the retina is subject to actinic injury from blue light. However, the lens strongly absorbs blue light as well but runs a high risk of possible opacification.
