I think their still a lot of scope for LED (semiconductor) technology to be a main light source for domestic use.
True, CFL life is less than advertised but the good ones, and some of the less than good ones, will last long enough and reduce operating cost enough to way more than offset the higher initial cost. The drop I saw in my electric bill after I switchedwas considerable more than the cost of the CFLs
There is no doubt that LEDs are going to replace incandescents and all forms of fluorescents, including CFLs, someday. However, same as CFLs when they first came out, there is a lot garbage hiding the good ones. LEDs will really take off when we start seeing more fixtures being designed specifically for LEDs, with built in voltage control circuitry instead of using LED bulbs with their own control circuitry designed to replace older forms of lighting. Another innovation that would make LEDs even more practical would be to start wiring buildings with regulated low voltage lighting circuits.
