The Energy Independence and Security Act of 2007 regulated 40-100W incandescent general-service lamps, requiring the lamp to either operate at a higher efficacy or cease being able to be manufactured or imported. In 2012, 100W lamps became affected; in 2013, 75W lamps are now under regulation.
For those wishing to retain incandescent lamps, there are two main options. First, one could simply buy a halogen screw-in lamp and save energy while retaining similar performance as an incandescent lamp. Second, one could buy a lamp that fits one of the regulatory exceptions.
One of these exceptions is for rough-service lamps. Among other manufacturers, AAMSCO sells rough-service commercial-grade incandescent lamps under the Ferrowatt brand and sells them direct to consumers. They are also rated at 10,000 hours. These lamps carry a premium.

The Department of Energy has been tasked with monitoring sales of exempt lamps and closing any loophole that is excessively used, indicating consumers are using it to bypass the Act.
