830nm Near Infrared LED Lights
These near infrared light therapy devices contain exclusively the 830nm type of LED. This highly potent wavelength has been extensively studied and proven. It is noted for its effects in deeper tissue.
Mixed-Infrared LED Lights
These infrared light therapy devices contain the same 830nm LEDs as found in the above products, with the addition of one other infrared wavelength - 760nm. The split between 760nm and 830nm is 50/50. 760nm is specifically noted as being the wavelength with the maximum penetration of all - being able to reach deeper cells that no other wavelength can.
