candlepowerforums.com may be a more appropriate place to discuss the merits and dangers of LED's. I found a more in-depth discussion of the Phatlight LED over there.
You might be interested to know that I obtained my Phatlight LED's to explore the potential healing qualities of far red light. Its dominant wavelength is listed as 625nm, which, as I understand it, is not far enough red for best results but it will have to suffice until I get some deeper red LED's (660-680nm) to play with.
I've only had one opportunity to try it (on a small flesh wound) and it seemed to work because it did heal quickly. But for truly meaningful results I should have inflicted a comparable wound on another finger and not irradiate that one. However, my dedication to science did not rise to the occasion. Call me a sissy but I will not intentionally inflict pain upon myself.
Further experiments will have to wait until I can get a suitable subject imprisoned in the pit in my basement.
