I put off buying a HappyLight for years, but decided it was especially needed in recent months.  It's been a rough year for most of us, and I already live with seasonal affective disorder, living so far north in Montana where winters are quite long and overcast.  This year as summer ended and a change could be felt in the air, I decided to be kind to myself before the darkness set in.  I am in my mid-sixties and suffered from SAD for far too many years.  I am very happy with my Lumi...perfect size to set on an end table next to my sofa.  Mine has 3 brightness settings which is really cool, so I could get used to it slowly.  I hope to have many more years of more tolerable winter living with my Lumi.  Thank you for the nice low-key design, too.
