No, government energy cops are not coming for your bulbs. But the traditional incandescent lightbulb that traces its roots back to Thomas Edison is definitely on its way out. As of January 1, 2014, the manufacture and importation of 40- to 100-watt incandescent bulbs became illegal in the U.S., part of a much broader effort to get Americans to use less electricity.
Stores can still sell whatever inventory they have left, but once the hoarders have had their run, that’s it. And with incandescent bulbs burning for only about 1,000 hours each, eventually they’ll flicker out.
The lighting industry has moved forward with compact fluorescents, halogen bulbs, and most recently and successfully, bulbs that use light-emitting diodes (LEDs), and General Electric (GE) and Sylvania have found themselves sharing shelf space with newer firms like Cree (CREE) and Feit.
Soon, the only places you’ll still see the telltale glow of a tungsten filament in a glass vacuum will be in three-way bulbs (such as the 50/100/150 watt), heavy-duty and appliance bulbs, and some decorative bulbs.
