Today is rainy and dreary, so I tried my SAD lamp for the first time. I'm not sure if it's psychosomatic, but I do feel better. The lamp I bought is called a "Travelite" by Northern Light Technologies. As some of you know I travel a little bit for work and I wanted something that I could take with me on trips. My lamp cost $225. Yes that is a lot of money, but if it saves me from dipping so low that I need to miss work it's well worth it.
Here's the link to Northern Light Technologies website:

Just wanted to share my experience.
