And a few specialized kinds of incandescent bulbs — like those that go inside ovens, and bug lights — are exempt. But most if not all other incandescents will struggle to meet the new efficiency standards, and the same goes for a more recent generation of halogen lights. “Going from an incandescent to an LED is like replacing a car that gets 25 miles per gallon with another one that gets 130 m.p.g.,” he said. With the new rules in place, the Department of Energy expects Americans to collectively save nearly $3 billion a year on their utility bills. In the past, a knock on LEDs was that they were more expensive to buy, but prices for LED bulbs have fallen rapidly to near parity with incandescents.
