In my dorm we had ceiling-mounted flourescent lights that were a nice, even, white color. They were quite bright and lit up the entire room evenly. For the most part, though, I preferred a desk lamp and a lamp by my bed for lighting, because I prefer it darker. I prefer indirect lighting, and I'd usually turn my desk lamp towards my desk and my bedside lamp towards the wall/ceiling. Of course I'd still use the ceiling light most of the time, but when I was in the mood to study, I'd turn it off and go to the others.
