This is a patch panel. Sort of looks like an old telephone operator's plug board

 These are board notes from a lecture that two of our interns presented explaining how the electricity gets from the power company to the lamp.

 "If I went with the identical lamp that's in this fixture, are you saying that it would be a more "brown appearing lamp"? You made that reference but am wondering if there is a lamp that is a more white appearing lamp as well. In the application that I will be using these lights, the distance to the stage is approximately 20 feet. I personally think that 575w is a bunch, although I am planning on hooking it up to a 600w per channel dim pack. Is it better to have the wattage there if needed, and just dim it when not? That sounds logical to me" ...
