I didn't notice a reference that your project will enclosed. If not, be sure to get UV protective glasses. I have a lightbox from Edwards Engineering through Bostick & Sullivan which will handle up to 11x14 that has eight black-light fluorescent bulbs and approx. 2in clearance from the printing frame. The fan is always on when the lights are on. Exposure times vary with individual negatives, paper and emulsion.
