There is one simple example program there, but I can understand you wanting more. Unfortunately, it may be a little while before I can get to doing that. I have a LOT of other stuff going on at the moment.

Yes. It should. It effects a "light" in a scene, not the material properties of an object.
I will try to write a small explanation of how/why the new commands work so everyone has a better understanding of them.
