I have now purchased a bunch of CFL's but to my surprise it is still not enough light, I still have aperture 1.8 while wide open with some gain. I'm using three 80 watts CFL's, and 8 40 watts CFL's and only 6-8 foot removed from the interview scene. I have five lights stands, using two 1 to 4 light adapters. This soft light (5500 K) even after doubling and tripling the number of watts is needing very close proximity to give adequate results (in the dark!). The reflectors are necessary and adding a diffuser cuts out too much light. Anyone have any suggestions how to increase the light output?
