I think two such lamps would let me get even enough light to print 8x10, and I don't have other equipment to support even that size yet -- a single would probably work for 5x7 and smaller.
For what it's worth, after a suggestion from Sandy King, I've been using a single spiral BLB (Feit Electric -- I bought mine from topbulb.com) in a reflector clamp light to make my Van Dyke Brown prints (6x9"). It works well -- exposure time is about 8 minutes with my digital negs, at a distance of something like 40-50 cm.
