  No, that's not the correct solution to the problem. He wants the light
emitted by light sources to fade to completely black, not the rays emitted
by the camera, which is a completely different thing.

  The correct explanation and solution were already given: The default
global ambient light level is (iirc) 0.3, and setting it to 0 does what
he wants.
