I like the lighting as always. I heard you had some problems with sphere previewing though? Does CS6 not have any way of mapping to a sphere good? I only used CS6E and I know that it's easy to sphere preview in that.
Did you try clicking one of those eyes under the 3d tab? If I remember right one of those turns off the light. You might have to turn up diffuse or ambient light though after you turn off the light source though (I think you click the lightbulb under the 3d tab to do that?).
