Back when I grew exclusively under lights, I used 50/50 (wattage-wise) 40W T12 cool white fluorescent and 100W incandescent bulbs, and was very happy with it.
I have been growing some plants recently - mostly seedlings - under the Hydrofarm fixtures with their 6500° bulbs, and they are doing great too.
