At least incandescent blubs don't burn down your house when they fail. The way the government is pushing the fluorescent bulbs is downright dangerous. Have they done their due diligence? Have they tested these bulbs extensively? The bulbs do not last nearly as long as they claim and they are incredibly hazardous (contain mercury) and must be very carefully handled to avoid breakage. They cannot be discarded in household garbage but must be taken to special hazardous waste depots. So they save a few kilowatts of energy. I'm not so sure that's a good thing if it costs even one person his/her life from a fire.
Moral of the story: If you have this type of light bulb and it flickers, turn the light off immediately and replace the bulb.
