Understanding Light Wavelengths
- 650 nm Red Light: This wavelength is absorbed by the surface layers of the skin, contributing to surface healing.
- 808 nm Near-Infrared Light: This wavelength penetrates deeper into tissues, reaching muscles and joints. The three 808 nm light beads are not visible to the naked eye.
