I posted some photos and circuit details of the red LED array I recently built
in the "Files" section.

 

I'm new to this group. I found it while researching the use of 670nm red light for wound healing. Also, last September I read an article "LED Light And Green Tea Cream Smooth Facial Wrinkles." (http://www.sciencedaily.com/releases/2009/09/090909103013.htm )

I told a friend about the article and later built a hand held unit containing 54 5mm 2800MCD red (670 nm) LEDs powered from a 6VDC wall transformer. I gave her the unit to see if it would actually reduce wrinkles using the green tea protocol.

I was wondering if anyone here is using red LED light and green tea for facial wrinkles, or has used red LED light for any other purpose.

Also, I'd be happy to share the circuit and construction details if anyone is interested.

Yeah, the shipping from europe is a killer, though.
I bought three of the 850 nm 1 watt LEDs from lightobject.com. One I mounted on
a handle with switch, with a 12 volt 1.25 amp adapter the resistors for the LEDs
are 30 ohm (I used ceramic 10 watters from old TVs). I used a nickel-plated
cabinetry finishing washer (15 cents) which I polished up with Brasso to focus
the beam angle from 160 degrees to maybe 30 degrees. Seems to work great for
brain, pain or Viagral uses.
