Interesting, I would have never thought that we have cells that use light as energy.

Also, is this deep red light found in sunlight as well? As in, does this treatment only work with light that is restricted to this wavelength, or does it work with any light that contains ample amounts of this wavelength?

I know its been coming up here and there that we are just not getting enough sunlight in general with everyone studying indoors, working indoors, exercising indoors, etc. Just seeing if this is a broader issue of people not spending enough time in the great outdoors.
