The Energy Independence and Security Act (EISA) of 2007 is going into effect starting January 1st. It will outlaw the manufacture of incandescent light bulbs, forcing everyone to switch to the compact fluroescent bulbs, halogen lights or LEDs. The EISA mandates a minimum light bulb life of 1,000 hours.
On January 1, 2012, 100W light bulbs will no longer be manufactured. Starting January 1, 2013, 75W bulbs will no longer be manufactured. And starting January 1, 2014, the 60W and 40W light bulbs will no longer be manufactured.
The compact fluroescent light bulbs are the curly bulbs. They use about 1/4 the power of incandescent bulbs and although they have a longer life span of incandescents, how long is a matter of use. The highest life spans quoted are for bulbs left on the entire time. Using them like a regular incandescent bulb drastically shortens the life span.
Halogens look similar to incandescents, use about 30% of the energy, are dimmable and are mercury-free. They are being manufactured and sold in stores now.
Solid State LEDs are being manufactured now and several companies make replacements for 25W, 40W and 60W incandescent bulbs. They are supposed to deliver an energy savings of 80% and are mercury-free. They are supposed to last for 25,000 hours but like CFLs, that number will vary with use. It's doubtful normal users will see that kind of life.
