Awesome innovation Marky! That is pretty cool in my opinion.
I also use visible red light therapy vs IR. I have read about 30 different research articles on red light therapy, which all contain a bunch of scientific jargon.
What I gathered from all this is that red light is part of the light spectrum that creates a physiological response from our bodies using photons(light has some physical properties), causing vasodilation(vessels relaxing increasing internal diameter of vessel), increased nitric oxide(signal chemical to create erection), cell mediation(control) of fibroblast, collagen, etc., excitability in mitochondria and increased ATP action at the cellular level.
I’m also guessing from the research that there is a therapeutic index(dosage that is optimum for what you are intending) as well as a non-therapeutic dose (too little of a dose rendering ineffective or too high causing more negative effects. There was a peer review chart with red laser and red cold led therapy conducted on various parts of the body as well as wound healing. (Light penetration through the particular part seemed to be an important variable like bone, muscle, dermis) LED and Laser seemed equally effective.
There were wide ranges. What I am hoping is correct is that the [intensity/energy level of the red light and proper distance] (x) times the duration of time for “treatment” (=) equals optimum effect that you are intending (vasodilation, increased ATP, cell proliferation, increased activity of healing)
Many people use a spectrometer or something like that to find the exact amount of photo energy being released by the red light. Then they calculate the distance the red light source needs to be for optimum dosage in nanograms or joules. Then they determine how long they need to expose the body part to the light.
The calculation(I forgot how I came to this calculation but saved it on my phone just in case) for specifically the penis is
3J/cm^2 per minute with the visible red cold LED at a distance of 12 inches away from the penis. The amount of power from the LED or laser should be ~680ng give or take a couple of hundred. I saw a conversion for calculating ng of light into joules of energy. (I am no math whiz)
Hope this helps or at least make you laugh.
