also....they are beginning to make the simple screw-in compact florescent bulbs in 'natural daylight' mode. I bought a package recently and put one in a lamp, and my son, who had no idea about it, walked past and said "I LIKE that light!"

I now have 4 of them about the house and may get more. (They are not as 'comfortable' for some areas/uses, but they may help. I DO miss sunlight during prolonged gloomy days.)
