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.
