The phase-out of inefficient general-purpose incandescent light bulbs concluded on December 31, 2013, the National Lighting Bureau advises. Starting January 1, 2014, it is a violation of law to manufacture in or import into the United States 60-watt and 40-watt general-purpose “A-line” incandescent light bulbs.

The phase-out process — required by the Energy Independence and Security Act (EISA) of 2007 (Public Law 110-140) — began on January 1, 2012, when 100-watt A-line incandescent light bulbs were phased out, followed six months later by a variety of inefficient incandescent R-series reflector bulbs and, six months after that, on January 1, 2013, inefficient 75-watt incandescent A-lines.
