Every time I see admins/operators sitting in rooms that are dark with the only light being from their monitors I am flabbergasted that they don't go batty.   The one time I worked in an office that was previously dark I asked the first day if anyone minded me turning on the room lights  and from that day on they were on whenever I was there.

The treatment is to sit in front of a bank of very bright lights for some period of time.   I'm not quite that bad but I did find after seeing that story that having my cubicle lights on during the day in addition to room lights did seem to make the winter months seem less grey to me.
Lighting affects people differently. Fluorescent lights can induce 
migraines in some, especially when the bulb is going bad. Also, the 
color temperature of fluorescents gives yellowish-green light that some 
find very irritating unlike incandescent bulbs which better mimic 
sunlight. I do not know what the color temperature of a computer monitor is.
