led screenRhythmatiques Technology includes Infrared and visible LEDs with reverse polarity so that during one-half of the cycle the current flowing in one direction to power one wavelength of infrared and one color of visible LEDs and in the other half of the cycle the reversed current would power the other wavelength of infrared and the other visible LEDs. This resulted in achieving a 100 percent duty cycle of both light energies and electromagnetic energy transferred between the instrument and to the subject being treated.
