A key issue to understand is that LLLT, as a category, covers a broad range of wavelengths. Individual wavelengths have individual physiologic results. The 635 nm wavelength is the monochromatic output that has been shown to be the best wavelength for improving cellular metabolism and therefore, improving wound healing.

Another important property of an effective laser is that it be a true laser, which, by definition, produces the emission of coherent light, generated at a precise, stable frequency, in a focused direction. Products that use Light Emitting Diodes (LEDs) are not true lasers. They produce non-coherent or random light, generating random frequencies. Coherent light energy is critical when treating the human body.

One more consideration is the optimum power necessary for bio-stimulation. The Arndt-Schulz Law of photo-biological activity, essentially states that “less is more” when it comes to energy for improved cellular physiology. The Erchonia® LLLT provides the best wavelength (635 nm) for cellular physiology at very low energy (2-5 mill Watts) to stimulate cells to function better. If the stimulation is too intense, there may actually be an inhibitory effect, or possibly degeneration or destruction of cells.
