I got my S.A.D. lamp from Northern Light Technologies out.
I got my lamp a few years ago when I was told that what I had was depression. (I have been told that before only it turned out to be cancer. This time, it really was depression, in some ways harder to deal with because of the stigma.) I was put on some anti-depressants for a year. I kept the dosage low with meditation and this lamp. I love this lamp! The trouble is, my cat hogs the thing!
