The use of NASA light-emitting diode near-infrared technology for biostimulation

Optimal LED wavelengths include 680, 730 and 880 nm
Near-IR induced a thirty percent increase in the rate of wound closure in these animal models.
Light-emitting diodes (LEDs) developed for NASA crewed spaceflight experiments offer an effective alternative to lasers. These diodes can be made to produce multiple wavelengths, and can be arranged in large, flat arrays allowing treatment of large wounds.
20% reduction in pain observed when LEDs used on Navy SEAL subjects
