I never had a SAD but I put full-spectrum lamps around my apartment, and my entire family approved of that. I think I feel better under that light than under the typical yellow-glow "warm" CFL light, I fell less tired.
The lamps are CRI 90-95, a mix of 5500K and 4000K; they produce pretty bright light (4500 lumen in smaller rooms, 6000 lumen in the bigger room, 3000+ lumen in the bathroom), and it's pretty comparable with the light from the window in the summer.
Note that I live in a NYC apartment which is not exactly spacious; in a typical house, I'd use 1.5 to 2x the amount of light. One of my friends who happens to have particularly large rooms uses 4 to 6 T8 tubes to light them; the tubes are full-spectrum ones used to light movie sets, something like KinoFlo.
