Summary:
Like photosynthesis - the correct wavelengths and power of light at certain intensities for an appropriate period of time can increase ATP production and cell membrane perturbation could lead to permeability changes and second messenger activity resulting in functional changes such as increased syntheses increased secretion and motility changes.

Red and near infrared light seem to be the most ideal wavelengths.

Red light and near infrared light acts on the mitochondria and at the cell membrane.

In in-vitro and animal LLLT wound healing studies comparing wavelengths, red consistently is more effective.

Shorter wavelengths are not as good and are more expensive to produce and have poor penetration; overall, they are a poor choice.

Near infrared light, while not quite as good, do penetrate better than the red wavelengths and are available in higher powers and at low prices.

According to live in-vivo experiments at Uniformed Services University Bethesda Maryland (a US military research centre) 810nm is the best penetrating wavelength.

It also happens to work well in LLLT nerve regeneration studies they are doing.
