Zawy! Thanks so much for coming on here man. Your site is seriously awesome. So much amazing info. I'm gonna sit down tomorrow and go back through it again.I'm glad to see they finally got this web site up and working again. I'm the guy with the http://heelspurs.com/led.html page. If the 810 penetrates better, it might be best for deep injuries, but probably not by a large amount. 830 should have about the same penetration. If anyone comes by Montgomery AL I can let you try on my LED helmet if I haven't butchered it for parts. I'd be surprised if there is any more powerful "helmet" in the world, but if you place a gallon zip-lock bag of about 1 quart water on your head then place a $10 500 W halogen flood light from walmart within 1 to 3 inches, then you should get a lot more healthy light energy to your brain than my helmet. When compared in terms of the energy from LEDs and laser, this should provide about 20 watts in the "mitochondria-active" range (1/3 of the 500 W comes out as light like the sun, and about 1/4 of that light is in the healthy range of 4 wavelengths, and about 1/2 of that is wasted in not being on a specific wavelength like the LEDs). The water is to absorb heat. This assumes the head is bald or shaved. It covers about 200 cm^2 so the intensity should be 20/200 = 100 mW/cm^2 which I think is 3 times more intense as my helmet but with maybe 3 times less coverage. Maybe I will do 4 of these 500 W halogen surrounding my head with some water blocking contraption. I guess I could make and sell a copy of my helmet for $800. My costs are $0.15 per 830 nm LED 1,500 LEDs, $20 for 12 circuit boards, $20 high-power supply, $5 solder. Approx $300 in parts, 10 hours pain-in-the-butt work. Actually, I could have them pulse at 5 times the intensity using a 20% duty cycle. There are only specious theoretical reasons why this type of pulsing will help, and it has to be at a very fast 50 uS on, 250 uS off speed, if not 10 uS on and 50 uS off. In practice I am still trying to determine if pulsing is better. So far the result are promising. If I put a fan and box on each board with pulsing, it can be 3 times stronger so that treatment would be 5 minutes instead of 20 to 30 minutes ($1,600... I was and will be selling the boxes individually for $185). Lack of strength is where all LEDs devices on the market are failing.
So, as someone who is way more knowledgeable and experienced than I am, I wonder if you wouldn't mind sharing with us some of your personal experiences with lllt. I think most of us are especially interested in your experiences with transcranial lllt but I'd also love to hear your thoughts on using infrared light on other areas of the body. What have you found as you've experimented on yourself? What has your subjective experience been like? Have you noticed any measurable improvements? Any warnings?
Thanks again for all your time and effort. I'll try not to inundate your with questions you've already answered on your site but any info you can provide would be greatly appreciated.
