If you need it, you will find it.

Just when I was planning out some shelving solutions to the art room, as well as thinking about expanding/replacing my light box, I walk past a junk pile on my corner.  In it is a L-bracketed shelf with two think supports, perfect for a counter-style shelf.  And Under it is a long fluourescent light setup, with transformers and sockets for four tubes.  God bless handyness, luck, and a junk-picker's eye.
