Oral IQ has designed PBM Light to be the best home device for light therapy on the market. Our patented devices contain three (3) different wavelengths which target different depths of tissue at the same time. PBM Light + is especially unique in that it trades the 630nm wavelength found on the original PBM Light for a 940nm diode. This wavelength is especially effective at deeply penetrating muscle and bone, reaching far deeper than most other home RLT devices on the market.
