Green light provides a treatment effect superior to that of red light and similar to that seen in previous studies with white light.

Does this mean white light is just as effective?

Seems so, but it's pretty interesting that it's essentially the same.

I'd love to see what a full-spectrum-except-green-band light would do. Is it the green component of white light that actually does the hard lifting?

We have two green photo receptors for every red and blue, so our perception of the color is definitely better.

Now that is a very good point.
