Remember the 100-watt bulb ban?
In December 2007, President George W. Bush signed the Energy Independence and Security Act (EISA), a law that mandated about 25 percent greater efficiency for household light bulbs between 40 and 100 watts sold in the U.S. by 2014. (EISA also required a higher mileage standard for vehicles and some other energy-saving moves.) The EISA effectively killed most — but not all — incandescent bulbs, because they couldn’t be profitably made to meet the new standard. Exempted bulbs included specialty bulbs, three-way bulbs, chandelier bulbs, refrigerator bulbs, and plant grow lights.
