I use a 150 Watt incandescent reflector flood and find with Lodima processed in Amidol and FP4+ processed in Pyrocat HD that I get paper d-max through the B+F of the film with a 12 second exposure (normal film processing). The light is about 2 feet above the paper. So a 300 Watt may not be needed. For Efke PL-100 (normal film processing) it took 35 seconds as the B+F was much greater.

I had replaced several of these bulbs with non-incandescent reflector floods a while back and kept them for printing use. So I don't know if they are readily available.
