Medical application for LEDs

    IANAD... (Doctor, Dork, whatever...) but I have heard of using HeNe Lasers (red, 632 Nm) for healing skin wounds and removal of various localized uglinesses of the skin. If there's any validity to that method, then IR Lasers might also provide some benefit. As for mutations, sorry. Light is considered a non-ionizing radiation, and as such, doesn't cause the DNA to get resequenced (mutated). Frequencies at or above "ionizing radiation" (X-rays, Gamma rays, etc.) do this to human tissue. Frequencies below just cause tissue to heat up (and possibly causes cell rupture) as it absorbs the energy.
