I lived in CKB (rooms identical to Mews) and I found the lighting to be good. There are wall and/or ceiling lights in addition to the desk lamps. The lights are white. Given that the rooms aren't exactly huge, it might not be the best use of space to bring a floor lamp. If I were you, I'd move in and see what you think. If you really find the lighting to be poor, Target is only 15mins away by the (free) bus and you can find something cheap there.
