Regular CFLs have color temperatures that are considerably warmer than daylight. I suspect their color temp also varies as widely as the prices. And since fluorescents have a much more discontinuous spectral distribution than incandescent lamps I could easily believe that could contribute to confusing AWB. I use some softboxes with daylight CFLs that work pretty well with bits or film. I chuckle at them being Compact FLs, as the suckers are a cluster of U-tubes about four inches in diameter and a foot long!
