CFL efficiency is perhaps true in US environment. But in third world countries are CFLs the correct solution? I do not think so, mainly for two reasons (a) disposal of mercury in CFL is a problem area (b) life span of CFL, which is the saving element that every body advocates, is not applicable for third world countries, because of poor quality of power supply. Most of the time lifespan of CFL works out to be the same as that of incandescent light bulbs.
