5 Graphs Proving We Have A Junk Light Epidemic

In Blog

I wanted to write this short blog when I came across some data from Goldman Sachs. The data was collected by Goldman Sachs on the rise of LED lighting over time. The authors of the report states that:

“The rapid adoption of LEDs in lighting marks one of the fastest technology shifts in human history”.

From an economic standpoint the switch in lighting technology to energy efficient LED from incandescent will save the economy, in the USA alone, $20 billion dollars in the next decade. This is all very well economically and environmentally speaking as carbon emissions are reduced and money saved. But we know from numerous scientific studies that the blue light emitted from these energy efficient LEDs are damaging our health.

Sceptics of this theory, despite a whole host of scientific studies, think that artificial light has always been around, but I want to highlight with raw data that this is not the case and the increase in LED lighting in the US and rest of the world has risen at an astonishing rate recently. Its not the amount of light rather than the type of light that has sharply risen over the last 10 years.

Graph 1

On this graph we need to focus not on the blue bars but the orange line. The orange line represents he cumulative number of LED lights installed over time. As we can see there has been a sharp increase in LED lights being installed since 2010. When we look at some data from another study in 2013 we can see that in the US sleep related issues sits at number 2 of the list of chronic illnesses whereas before 2010 it did not even feature in the top 5!

Graph 2

If you thought the first graph is worrying you will not feel much better about graph 2. Graph 2 shows the market share LED lights have had, have today and projected to have by 2025. In 2010 LEDs accounted for 1% market share, in just over 12 months in 2020 they will hit 69% market share and by 2025 a staggering 95%. If this trend continues we will see an even steeper rise in sleep complaints, metabolic diseases and obesity levels. Exposure to LED blue light in the evenings and during sleep by even a small amount increases insulin resistance which leads to diabetes. If LED lights continue to steel market share as predicted they will also continue to steel our health.

Graph 3

Graph 3 only solidifies the two previous graphs, as it shows that residential lighting purchases have steeply risen in favour of LEDs. In 2012 only 8% of residential lighting was LED purchases but today in 2018 its at 72%. The more LED light we put into our homes the more blue light we are going to be exposed to. This is heavily impacting the rising rates of metabolic diseases we are witnessing today.

Graph 4

Graph 4 from a biohacking perspective doesn’t mean too much other than to reinforce the fact that LED lights are being preferred incandescent lights. Its worth noting at this juncture that incandescent lights are less energy efficient that LED lights. This is the whole reason LED lights were introduced. I use red incandescent lights in my home and I have to replace them far more frequently that LED lights, but its far better for my health and wellness.

Graph 5

Graph 5 is very concerning as the catalyst for the explosion in LED lights being adopted has been the near global phase out of incandescent lighting. This has been mandatory in all major global markets. In our biohacking circles its often commented how hard it is to obtain incandescent lights and this graph shows us why and that we aren’t imaging it!

Final Thoughts

These 5 graphs are a major concern for the savvy biohacker as the growth of LED lighting will only increase over the next 6 years according to reliable forecasting and statistics. We can hack our homes fairly easily, but we cannot hack our external indoor environments very well. Therefore, it is suggested you do the following:

  • Grab some good quality daytime blue light blocking glasses here
  • Grab some good quality night time blue blockers here
  • Get some red-light bulbs from here
  • Get some black out curtains here or a silk sleep mask here
