Thanks for the data. It looks like I made a big mistake. In frustration I tore the scene down to just the table lamp floating in mid air so I could get the cans-spots located correctly and circle the lamp with the camera and not have the walls or other props get in the way. After thefixer mentioned volumetric lighting I did a search on the tuts here and found one that was a spot light on a character. It talks about atmospheric lighting etc. But one key issue it mentions is you need a background to make it work correctly. I did get it to cast a yellow light down onto the  lamp it's self. Up out of the shade nadda. I assume it is because there is no background going up and it is using the lamp body going down. Need to reassemble the scene and try again based on your suggestions. If I added any amount of slight ambient light, it seemed to over power the spot. But I think I just need to put the scene back together and try what you have mentioned. Thanks a ton for the assistance and getting me headed in the right direction.
