Well, before the lights go out I'd better finish up my phrase search of the U.S. Constitution to at least have a legal reference for where "incandescent lightbulbs" are specifically included in the enumerated powers of the federal government ... likely "incandescent lightbulbs" are tacitly covered in the ever-growing "penumbra" of "promote the general welfare," a serious concern which the Founders warned of. Cheers!
Article 666 of the Constitution states that the document expires in 2021—from that point forward .gov can do whatever it wants.
