I just finished an industry analysis for the light bulb industry in the US. The LED technology is advancing at such a fast rate that although they are prohibitively expensive now, in 5 years they will cost less than CFLs and provide higher quality lighting. The big three light bulb manufacturers (GE, Philips, and OSRAM), which make up 95% of the US market, are buying LED firms like crazy. LEDs last about 10x longer and use 1/10 the electricity of CFLs as well. CFLs contain a small amount of mercury which will help speed adoption of LEDs.
