The SCAMS & MYTHS CREATED by lighting industry
(Exceptions are always there)
Question: Should be worried about the knowledge of lighting designers and the manufacturers, when it is referred to our health and wellbeing from LEDs being produced, marketed and specified?
Answer is YES, largely (worldwide there are very few who possesses this knowledge – Physiology and light)
The first Cognitive Bias – Awareness
The physiological balance of the indoors cannot be achieved either with an individual or with one type of organization be it an architectural firm, PMCs, Lighting designers, interior designers, electrical consultants, planners etc.
The Second Cognitive Bias – The Misconception
Humans are made up of seven trillion trillion trillion atoms including 89 billion neurons. Thus physiology is an essential subject before anyone or any organization delve into the benefit of lighting systems for WELLBEING (circadian, behaviour, metabolism, ATP etc)
We often hear the statement that human-centric light is the mimicking of the natural form of light concerning the tunable colour temperatures (2700K to 6500K etc.). By implementing this kind of lighting system along with the equivalent melanopic lux levels and stabilizing the circadian stimulus our circadian response will be aligned to the circadian functionality. IT IS NOTHING MORE THAN A PLACEBO AND A SCAM.
Apart from the inappropriate ways of marketing circadian-based lighting system, we are unaware of the true parameters of light and the respective benefits but hardly any lighting organization are working towards this. For example, inducing NIR/FIR along with the UVB with the respective irradiance favourable values and the exposures.
The perilous ways of marketing the concept and the lighting systems will not only mislead but will negatively contribute to our health and wellbeing.
I have always advocated that the lighting fraternity is no less than the medical fraternity, thus I will use the term prescribing the lights rather than specifying the lights as the light is one of the prime zeitgebher which influences the molecular mechanisms along with the psychological aspects and behaviours.
But the large and corrupt lobby is doing nothing more than the cognitive bias of a community anxious to generate revenue only in by spreading the placebos like improving the sleep-wake behaviour of occupants with their so-called tunable white light with a full spectrum.
The created impasse can be easily dealt with once the buyer/user start doing some suggested ways like:
A. The harmful outcome of the specified/installed light along with the misleading specifications used as a placebo becomes the basis to file lawsuits against all producers/specifiers of lighting products.
B. If the circadian rhythm is already aligned then who proved the circadian lights were required and on what basis? Who did the pre and post-audit? What were the parameters?
Though the platforms like IWBI, IES and CIE are contributing a lot so that the followers, members and the people/organsiations associated with the building industries are aware of these kinds of issues, some platforms like IALD / ISLE must start contributing in many efficient and pragmatic ways rather than focusing on events and art from lighting industry (though those are important too, more important is the harmful ways of the LEDs being specified/used or being misled.)
Driving through the paths based on mythical logics, finagled by the team who are marketing the lights based on revenue generated by swathing up the lighting products (especially offices, health care units and residences) with the maquillages, and with no physiological research-based (in a holistic form) – are the reasons that why lighting is losing its credibility against other zeitgebers (knowing the fact that light is the prime zeitgeber for all the planets and our solar system)
We are heading for the crash to more serious culpability, if not outright liability for failing to respond.
