A lot of information on the intertubes on the energy bill passed by congress, like engaget, has incandescent bulbs banned by the year 2012. In fact congress did not specifically ban incandescent in favor of florescent technology or any technology. Trying to find a news source which actually reported the specifics was difficult, a article on thedailygreen.com has more information.

Under the measure, all light bulbs must use 25% to 30% less energy than today's products by 2012 to 2014. The phase-in will start with 100-watt bulbs in 2012 and end with 40-watt bulbs in 2014. By 2020, bulbs must be 70% more efficient.

They also say that florescent bulbs meet the 70% standard. What happens to bulbs higher than 100 watts? Scientific American had this to say

About two dozen categories of light bulbs are exempt from the U.S. law's efficiency requirements, including oven and refrigerator bulbs, candelabra lamps, plant lights, replacement traffic signal bulbs and the summer necessity -- the yellow bulb that doesn't attract insects.

Althought they will have a tough time meeting the 70% standard in 2020, incandescent are far from dead. I'm all for more efficient bulbs, but I am not a fan of the current compact florescent technology. I spent a small fortune on dimmable CFL bulbs only to be left with a pile of dead CFLs of which most lasted less than a year. I am not impressed with their dimming ability either (all of my switches are dimmable as part of my home automation system).

Whatever happens, incancesdents will get more efficient and CFLs and LEDs will get better/cheaper, and I will be happy to replace them with whatever works best. It may not matter anyways, 2012 is the end of the world.
