This thread was split from -- Building a 'SAD' Light Therapy box.
I have recently built a portable light therapy device to help with my Seasonal Affective Disorder. One thing I learnt was that wavelength is important. Blue and greens (450nm - 550nm) are good for treating SAD, but just using white light without knowing how much blue/green is in there is a big no no. Using blue or green LED's with an output of about 300 lux (measured at the eye, not the light source!) is the way to go.
