In an effort to reduce energy usage, greenhouse gas emissions, and dependence on foreign sources of energy, the Energy Independence and Security Act (EISA) was passed and signed into law in 2007.  As a result of this law, regulations will set minimum efficacy standards and, for the first time, a minimum rated life of 1,000 hours for general services incandescent lamps.  Since most incandescent lamps cannot meet these requirements, several of the most popular ones will be phased-out by January 1, 2014.
