Have you been officially diagnosed with SAD? If you have, your Dr. might be able to give you a medical device prescription for a high powered light. From what I have read, (my mom suffers from SAD) you need to sit in front of the lights for at least 30 mins. in the morning. I think you would have to get mighty close to a Verilux bulb. Ultralux or Blue Max might be better. You need at least 10,000 lux, so make sure you get that with whatever light you choose.
