NEW Dual Infrared & RED Light Therapy Speeds Healing 120 Leds
This LED array is set up so you can operate the red and infrared leds separately or together. You can select which ones you want to use with the two switches. It has 120 LEDs - 8 rows of 8 LEDs each of the 660 red, and 7 rows of 8 LEDs of the 880 infrared. WAVE LENGTH OF CELL TISSUE About ten years later at the University of Chicago, researchers discovered that the average wavelength of cell tissue in the human body ranged between 600 nanometers and 720 nm; 660 is the mid-point. So in essence, the reason a 660 nm works better than any other single frequency is because it is closer to the resonant frequency of cell tissue. The other reason is that 660 nm absorbs better in hemoglobin.Led Unit Measurements are: 5 inches Long plus 1/2 inch for switches 2 3/4 Wide 7/8 Inch thick
