I’ve had a few queries about using high powered LEDs, the logic being that if low powered LED strips can improve the health of neurons, then lots of low powered LEDs or high powered LEDs will do a better job. If only it were that simple…
Prof John Mitrofanis and others have shown very clearly that there is a Goldilocks Effect. They use a more scientific term, but it is the same thing.
1. Too little red/near-infrared light doesn’t do very much at all.
2. Too much red/near-infrared light can cause problems for the neurons.
3. The just-right amount of red/near-infrared light is perfect.
Prof John and his team have been able to define the “just-right” dose at the neuronal level in mice. But we have no such knowledge for humans. So we have to be cautious. Very cautious.
So, please don’t use high powered LEDs. Start at a low level of red light exposure, as we have done.
Remember that we are at the very beginning of understanding of trans-cranial lights. There continues to be wonderful research work being done and as it appears, I’ll let you know if and how this changes the approach to DIY light hats.
What I do know at this stage is: Less Is More.

We have made the shell of our Eliza bucket, the 670 and 810nm wavelength lights have arrived from the site Recommended in China and our clever son-in-law is planning to solder them together. In light of your recent Goldilocks Effect post what length out of the five meter rolls would you recommend using, ie all of each roll, half, etc? We are planning to be able to switch between wavelengths, using 25minutes on 670 then 25 minutes on 810. This is based on earlier posts and info from “ The Brains Way of Healing”.. We’d love to have your thoughts before we solder!
