"The Biden administration late Friday proposed a rule that would impose a lightbulb efficiency standard after the Trump administration declined to do so.
If implemented, the Energy Department proposal would establish a “backstop” barring the sale of lightbulbs that don’t meet a minimum efficiency requirement.
The move is expected to shift the market toward more-efficient LED light bulbs and away from incandescent bulbs.
The Biden administration argued that the move would both benefit consumers and provide climate benefits."
