In the May discussions on LED Phototherapy Light wands, Ivan Anderson say "I have single red LED's that produce 6,000 mcd."
Where can I get 6,000 mcd LED's? I have searched the internet and found some 9,000 mcd LEDs but they were only 630 nm. Can anyone tell me if that wavelength is less effective for treatment? I just received some 4.000 mcd LEDs from BGMicro, but on my tests they have light output that is approx. 20 % lower than the 3500 mcd I have from a different supplier. I also tried a few of their clusters that were discussed here. I found that most of the individual LEDs had very poor light output. If I remember correct, there were only 5 out of 27 of the red ones that had reasonable brightness left in them. I have built 2 light wands and the tests have been very encouraging. One man has a bad rotator cop in his shoulder, and the light has substantially reduced his pain. The second unit is being tested by a lady with a sprained ankle. She is reporting that her swelling went down after the first treatment with a reduction in pain. I also have a question for Brooks Bradley. Ivan posted the construction article in May that shows a grid with 5/8" squares with LEDs in alternate points, which gives a 1 1/4" spacing between units. How important is spacing? I built one before I had those plans and spaced the leds touching each other. This gives a greater concentration of light in a small area. Have you done some research on effectiveness as it relates to spacing. I have very much appreciated your sharing on this site Brooks, and look forward to learning more from your well of experience. Thank you Dave Sawayzky
