That's like saying, "There's no gas-powered car ban. Sure - you can have a gas powered car... What was that?... Yes, it's true that you can't buy or sell a car like that in the United States anymore unless it gets 100MPG, but.... What?... *Sigh* Yeah, yeah, yeah - it's true that after decades of research and effort by the auto industry no 100% gas-powered car has even come that close to that number, but it's not a car ban. Are you listening this time? IT'S... NOT
As for the car analogy, even at 100mpg, you still only use one quart to go and three are wasted as heat and friction.
I just saw an article pointing out an effort in Texas to go around this light bulb efficiency mandate by producing and selling the bulbs within the state.

I believe this has merit. This is the same argument to allow medicinal marijuana in California, and avoid firearm controls and taxes in Montana. The federal government is only empowered to regulate commerce among the states, not within them. If the lamps never enter or leave the state then the federal government has no jurisdiction.
Anything that moves backwards happens in Texas.
