A SAD lamp designed specifically for SAD it filters out all or nearly all UV. Sun lamps don't necessarily filter out the UV and sometimes the world is misleading, they can emcompass tanning lamps which definitely DO have a link to cancer.

@Blue_Bird That would be a great birthday present as long as it doesn't trigger mania in you, but no way to know until you try. You don't have to spend a ton to get one that helps. I spent around $35 (with a $5 off coupon) on Amazon on the lamp I have. It doesn't have many bells and whistles though, you can't adjust the intensity of the light, but for me, it works just fine.
