Under the rules, incandescent and similar halogen light bulbs will be prohibited in favor of light-emitting diode, or LED, alternatives. While U.S. households have increasingly switched to LED light bulbs since 2015, fewer than half of households reported using mostly or exclusively LEDs, according to the most recent results from the Residential Energy Consumption Survey.
Overall, 47% use mostly or only LEDs, 15% use mostly incandescent or halogens, and 12% use mostly or all compact fluorescent (CFL), with another 26% reporting no predominant bulb type, the federal data showed. In December, the DOE introduced separate rules banning CFL bulbs, paving the way for LEDs to be the only legal light bulbs to purchase.
