I’ve been in a light therapy Rabit hole as of late. There’s been a lot of research around it, and even historical accounts of Light Therapy where specific colours were used to restore health among ancient cultures in Egypt, Greece, China and India.
What are your thoughts? 
How would they divide up the light?
Seems like nonsense.
This guy (Ari Whitten) wrote a book called Ultimate Guide to Red Light Therapy...and also has an exhaustive light therapy guide here.

Sounds interesting! Will look into it?
