LED in ears cures SAD!!

Listen guys. This is going to sound like SCI-FI i know, but bear with me because this is awesome news! :)

Scientist in finland have found out that if you insert a pair of very strong LED lights in the ears, it cures SAD.... Simple. Yes. Weird. Yes. Effective. Yes, because they have allready launched a product thats on the market now caled "Valkee": http://www.arcticstartup.com/2010/01/22/valkee-projects-light-onto-your-brain-literally/

Its a portable lighting device, looks like a walkman, but it costs like 200 euros!

Now I am really curious to make a DIY set for myself, but a bit unsure how strong the LED should be, what size, color, and if there is risks like burns/ shock. I asked my local electrician and what he could produce was a white 20 MA LED.

What do you think!!?

According to the study, 1 lumen was effective at treating SAD. It looks like 20 mA white LEDs are more than bright enough.You can dim it further with resistors if you prefer.

Blue and cyan may work too but the longer the wavelength, the safer it is. I have never used the Valkee before. If you have, please let me know about it. There is little if any risk of getting shocked from 3.6V but shorts can burn at any voltage.

Here's an article about my opinion

Have you considered a hat version of a lightbox? I've been thinking of modding a Luxion LED headlamp with a blue LED and attaching it to a hat visor facing inward.

Umm... Is there a circuit diagram?

Thanks ewil. Your circuit kicks'a. I've got some questions, which I'll put on the other thread. Brian
