This is the best summary I could come up with:
SAN FRANCISCO (AP) — Get ready to say goodbye to the once ubiquitous incandescent light bulb, pioneered by Thomas Edison more than a century ago.
The rules establish strict new efficiency standards for bulbs used in homes and businesses and bans the manufacture and sale of those that don’t meet those requirements.
But those requirements carry a bit less heft than they would have several years back, largely because advances in LED technology and manufacturing have dramatically lowered prices and improved quality.
Between 2015 and 2020, for instance, the percentage of American households that reported using LED bulbs for most or all of their lighting jumped more than tenfold — from 4% to 47%, according to the Energy Information Administration, an independent federal statistics agency.
As the rules reinforce existing market changes, the Energy Department believes that U.S. consumers can save almost $3 billion annually on their utility bills.
