Bush (you remember him) signed an Power Invoice that, among other things, supposed to make America extra energy efficient. It included regulations that may finish the manufacture of wildly inefficient lightbulbs. Some political shenanigans ensued, however the quick version is that in 2012, the phaseout of conventional incandescent bulbs began, beginning with the 100-watt varieties.

Frequent switching can be one reason they burn out early. Listed below are a couple of different issues that can do in a CFL.
