California made the incandescent light bulb history on Jan. 1.
As of that date, the state’s energy efficiency standards for the everyday screw-based light bulb became too stringent for the old technology to meet. By 2020, the standard will extend to the rest of the nation, signaling the end of the incandescent era.
There are an estimated 250 million light sockets in California still containing inefficient bulbs. After all of these sockets switch over to a more efficient alternative – CFLs or LEDs– California consumers and businesses will save an estimated $1 billion every year on electric bills.
Bulbs manufactured on or after January 1, 2018, and offered for sale in California must achieve a minimum efficiency level of 45 lumens per watt—three times more efficient than incandescents. The LED bulb that replaces the 60-watt incandescent bulb only uses 10 watts of power to deliver the same amount of light.
