Nobody seem to have mentioned the very poor power factor that most CFLs operate at – somewhere around 0.5 I believe. While this may not concern individuals who are only paying for kWh the cumulative effect in the supply network means there can be lots of reactive power to provide. The fact that they cannot be dimmed makes them unsuitable in many applications. Fittings designed for CFLs seem to be a long time coming which means more light is often required to achieve similar useability becasue much is wasted by the poor optics of the fitting
