any recommendations for a proper light bulb for the exposing lamp? frosted or clear? what wattage to start? ge, phillips, other?

right now the films and papers I'll be using will be tmy-2 and acros in 4x5. Nothing yet in 8x10 , I don't have the camera yet . I'll be using ilford matte fb paper, as well as slavich single weight, and EMAKS G3.

please advise
