Wow... Lights can be confusing... I locked my poor computer up for abotu 15 minutes at one point trying to render something. Here is my latest attempt... Still not quite there with the cloudy glass I think.

Brian, I'm not trying to make the two tone as it seems in your render. I'm more than likely going to attempt two different lights. One metalic that reflects the light and the other more lampish looking where the light shines only through cloudy glass.
