Compact fluorescent bulb or CFL
WEST SACRAMENTO, CA - As of this week, 100-watt incandescent bulbs manufactured after Jan. 1, 2011 can not be sold in California stores.
The new law means a former 100-watt bulb will have to use 72 watts or less, or be 28% more efficient. The 72-watt replacement bulb will provide the same amount of light (measured in "lumens") for lower energy costs.
Adam Gottlieb, spokesman for The California Energy Commission, said the Golden State is the first state in the country to enact the new light bulb efficiency standards outlined under federal law.
The standards, aimed at saving money by improving light bulb efficiency, are part of the Energy Independence and Security Act of 2007, which will be adopted by the most of the United States on Jan. 1, 2012.
Gottlieb estimates Californians will save more than $35 million in electricity costs in 2011 by enacting the new law early.
"The quality of the light is up to the consumer. The standard is just saying that the bulbs on the shelves are energy efficient, they put out the same amount of light and save consumers money," Gottlieb said. "They protect the environment because it reduces the need to build additional power plants, were reducing our greenhouse gas emissions and also saving the state's carbon footprint."
Similar standards for 75-watt, 60-watt and 45-watt incandescent bulbs will fo into effect in California over the next few years.
