You can set some "global" scene lighting properties using something like this:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/NoShading

I've never done this, but for spotlights I'd probably start by looking at

Unfortunately there are no examples of how to use this class - maybe
someone will write one for you.
