My parents just had a CFL fail after three months of use, and it failed with a large explosion sound and the strong smell of something burning. They quickly got the light out of the house to keep it from stinking further. I've had one that failed within a year and the plastic base had gotten extremely hot in one spot it distorted the plastic. We need to move past CFL quickly and into something else like LED. I'll also throw in my two cents regarding incandescent and how we rely on the heat generated almost 3/4 of the year, I don't want a more efficient light most of the year. Sure wish Washington would just leave us all alone and worry about the important stuff like financial stability and commerce, national defense, and not much else, well, the national parks are pretty cool.
