Falling prey to the hype around CFL lamps and their energy efficient, earth friendly ways, I have been using them for a while around my house. But my overall experience with them has not been very good. They dont last as long as promised; in many cases their life is less than the incandescent predecessors that they replaced. I am sure it reduced my electricity bill - but on a cost benefit analysis, I am not sure it passes the test. With a cost anywhere between 10-15 times ordinary bulbs, their life is pretty low.
