But of course doesn’t justify banning ordinary light bulbs:

If new LED lights are good, people will buy them – no need to ban ordinary light bulbs (little point).
If they are not good, people will not buy them – no need to ban ordinary light bulbs (no point).

The arrival of the transistor didn’t mean that more energy using radio tubes had to be banned… they were bought less anyway.

In any case:
Since when does America need to save on electricity?
There is no energy shortage, there are plenty of local energy sources, Middle East oil is not used for electricity generation.
Consumers pay for any power stations, just as they do for factories and shops generally.
Certainly it is good to let people know how they can save energy and money – but why force them to do it?

Does your light bulb give out any gases?
Power stations might not either:
In Washington state practically all electricity is emission-free, while around half of it is in states like New York and California.
Why should emission-free Seattle, New York and Los Angeles households there be denied the use of lighting they obviously want to use?
Low emission households will increase everywhere, since emissions will be reduced anyway through the planned use of coal/gas processing technology or energy substitution.
Again, the savings – and their value – can be questioned.
