The lighting for that realistic GPU renderer(the perfume, jewelry, bathroom counter etc) is done without direct lights. Its more of a brute force global illumination. You create the set and put the objects in it. There's a 3d daylight system which will cast ambient light through the windows and bounce rays around the scene. Most of the work is in the modeling and surfacing.
