The limited controls we have under lighting are under the view
options. I think the choice is just headlight or light kit (6 lights).
The bug I put in the bug tracker to improve that sits idle. Most
likely you can go to the python shell and access lighting manually but
I've never tried and don't know how difficult it will be to access and
move them.

Try changing the material at the bottom of the display tab to one of
the dielectrics, then you can control the refractive index. Also, make
sure you are not color mapping some field as materials are only in
effect when coloring the whole object a particular color (the
rationale is data fidelity).
