Yes, ‘Tough Spun’ (fiberglass diffusion) is an industry standard and is great if you can get your hands on it. Vellum is the ‘poor man’s tough spun’. Be advised that tough spun just like vellum will burn as well when subjected to long hours on end under hot lights. CFL’s are very good, but you’ll need more of them to get the equivalent wattage output as you get with tungsten bulbs. Also, off the shelf CFL’s work well but aren’t color balanced like pro cfl bulbs are. The also don’t cost as much! When you start getting into the bigger CLF equivalent bulbs (150w and larger) you’ll have to make sure your lighting fixture is properly supported. Those bulbs get pretty unwieldly and front end heavy which will cause your fixture to fall over destroying your bulbs and releasing that toxic gas and glass fragments.
