Barack Obama banned incandescent light bulbs
Congress passed a law requiring incandescent bulbs to be more efficient in 2007
This false accusation stems from a bill that Congress passed in 2007 -- and which was signed by President Bush -- called the Energy Independence and Security Act. While the law set efficiency targets for light bulbs that took effect in 2012, it did not ban incandescent bulbs. In a 2010 Q&A, the Natural Resources Defense Council’s Noah Horowitz explained:
The rules phase out inefficient lightbulbs in a technology-neutral way. In other words, the rules don't specifically ban incandescents. Nor do they specify LEDs or CFLs as replacements. The rules simply set efficiency targets that come on line in two steps, first in 2012 then again in 2020.
Beginning in 2012, common household bulbs must use 30 percent less power. That means today's incandescents (which convert only 10 percent of the electricity they consume into light -- the rest is given off as heat) don't pass the new code. Today's incandescent 60-watt bulb puts out about 900 lumens of light, or about 15 lumens of light per watt of electricity. The 2012 standards calls for bulbs of around 20 lumens per watt or better. By 2020, the rules call for a further improvement in efficiency, to about 45 lumens per watt, about three times more efficient than today's bulbs. That's about the efficiency of a CFL today.
