paragraph_text: U.S. transition to LED bulbs
  
  In the United States, incandescent light bulbs including halogen bulbs stopped being sold as of August 1, 2023, because they do not meet minimum lumens per watt performance metrics established by the U.S. Department of Energy. Compact fluorescent bulbs are also banned despite their lumens per watt performance, because of their toxic mercury that can be released into the home if broken and widespread problems with proper disposal of mercury-containing bulbs.
