Lisa, The following link provides some excellent technical information:
http://heelspurs.com/led.html Since you are looking for a very low cost option here are some choices. You can buy one of these for $2.90 plus shipping and connect it to 15 volts DC. The wavelength of the LED is 632 nm, which is good. http://www.futurlec.com/LED/LEDCLR15.shtml If you can determine pin numbers and solder wires you can wire 3 of the following displays in series and connect them to 6 volts. This will be complicated for someone who has not done something like this before. They cost $1.40 each plus shipping. The wavelength of the LED is 660 nm, which is about ideal http://www.futurlec.com/LED/LEDM57R.shtml A little higher in cost at $8.90, plus shipping is the following. It is simple to connect since there are only two wires and it uses 12 VDC. The wavelength of the LED is 630 nm, which is still good. http://www.futurlec.com/LED/LEDMR16RD.shtml All these low cost options use LEDs rather than laser diodes. I expected laser diodes to be more efficient and give out more light for the current input but from what I have found there is little difference in efficiency. I would not hesitate to use these devices. I wouldn't bother with blue LEDs for your application. It won't have much affect except to look pretty. Here are the pages that provide the prices for the options above. http://www.futurlec.com/LEDMatrix.shtml http://www.futurlec.com/LED_Lamps.shtml I hope this helps some. - Steve N - From: Lisa [mailto:[email protected]] Sent: Wednesday, May 19, 2010 1:18 PM To: [email protected] Subject: CS>Lasers and thinning hair Hi All, With intrigue I've been following the email trails on laser therapy. I am greatly interested in trying this out on my thinning hair patch which I believe is a result of a thyroid issue (which has now been resolved) OR possibly following the hcg diet 2 years ago. Regardless, I have this one spot in the front of my head which has thinned - I can't seem to tell if there's any improvement and would/have tried a variety of different things to fill it in. Since I haven't worked in two years, the lasers out there are way out my reach also...can anybody suggest something that I can put together at home? I do have a laser pointer which actually has several tips on it (which are a variety of shapes). Will this work? I could probably spend up to $30 on something but that would have to include S&H. eBay has a laser comb/brush which has red and blue LED's...it's $50 but I'd wait to buy that if I knew it would work (it would come direct from hong kong). Soooooo...do any of you brilliant minds have any ideas for me please? Lisa -- The Silver List is a moderated forum for discussing Colloidal Silver.
