In 2012 Lumens ( a measure of light) will replace Watts ( a measure of electricity usage) on that package of lightbulbs; and incandescents will fade into history over the next 2 years.
According to Penni McLean-Conner, vice president of customer care and energy efficiency for NSTAR
“Beginning in 2012, new federal standards for energy efficiency will usher in an era of improved lighting options for consumers. If we take time now to familiarize ourselves and our customers with the coming changes, we’ll all be more informed shoppers when the new standards go into effect.
The Energy Independence and Security Act (EISA), signed by President George W. Bush in 2007, requires that light bulbs use less energy beginning this coming January. It’s a common misconception that the Act bans incandescent light bulbs. It actually doesn’t. But the EISA’s minimum efficiency standards are high enough that the incandescent lamps most commonly used by consumers today will not meet the new requirements. So the Act will essentially eliminate most traditional 100-, 75-, 60- and 40-watt incandescent light bulbs between 2012 and 2014.”
