The array is a 660nm red array 36 LED and a 880nm infrared 36 LED. The red is rated at 2500mcd fo each LED. The infrared I'm not sure of. I did several 10-20min seesions with the red LEDs in each eye. Sometimes I closed my eyes , sometimes I kept them open. As I looked at the red LEDs the color seemed to change from red to yellow to green. Then finally when I finished the color seemed to be almost blue for a few minutres afterward. I assume this is because the rods and cones were overstimulated by the bright LEDs. I'm sure this would be considered radical and dangerous by many. After hearing about people sungazing with no ill effects I decided to try the LED array. The 880nm infrared array has been beneficail for my back injury with only 1 20min session. My wifes knee injury requied several 20min sessions to bring relief to her knee. My liver pain is about 10% of what it was as a result of several 20min sessions with the infrared.
I bought the array from http://www.theledman.net/ Steve
