I forgot the name but the company is in Gaithersburg Maryland...I have a desk lamp I have had for three years. I turn the light on form Oct 1st thru the end of March and I have it on in the morning for about an hour and a half while I am on the computer. It helps with SAD...seasonal affective disorder..I am not sure its help for bi-polar illness. I have yet to replace the bulbs. The company is very good with offering a payment plan..non-interest bearing. I remember I called and found out some info and then heard the prices and thanked them and hung up. They called back with the fact I could pay monthly without interest and gave me some of their opitions. I took the desk lamp..can't remember exactly the price ..maybe around 250.00...they are so good with working with you!! I think its called sunbox company. Oh also they send you the lamp before you are done paying and they do not care about your credit rating!!

I found it on the internet. You can go on-line and look at the web site or call:
Call 1.800.548.3968 or 1.800 LITE YOU
19217 Orbit Drive, Gaithersburg, Maryland 20879
p.s. they also have visors etc...much cheaper and work well. Do go to the web site though..very interesting what they do and who they work with!!!

Good luck;
