More complaints about energy-saving bulbs
"Somebody decides to save a little money somewhere and suddenly we have hundreds of thousands of (bulb) failures," said Victor Roberts, an independent expert in Burnt Hills, N.Y., who conducts failure analysis testing on light bulbs.
Compact fluorescent bulbs comprise 11 percent of the market for bulbs in the United States, but consumers increasingly complain the bulbs burn out early, The New York Times reported.
"In the pursuit of the holy grail, we stepped on the consumer," said Michael Siminovitch, an energy expert at the University of California, Davis.
Overall, the energy-saving bulbs are of good quality, but it's difficult to keep tight quality control on a cheap, mass-marketed item, many of which come from China, said Alan Feit, vice president of Feit Electric.
"While manufacturers try to inspect all incoming materials, one little mistake may cause a performance problem," Feit said.

How Bitcoin's vast energy use could burst its bubble
LONDON - The University of Cambridge Centre for Alternative Finance (CCAF) studies the burgeoning business of cryptocurrencies.
It calculates that Bitcoin's total energy consumption is somewhere between 40 and 445 annualised terawatt hours (TWh), with a central estimate of about 130 terawatt hours.
The UK's electricity consumption is a little over 300 TWh a year, while Argentina uses around the same amount of power as the CCAF's best guess for Bitcoin.
And the electricity the Bitcoin miners use overwhelmingly comes from polluting sources.
The CCAF team surveys the people who manage the Bitcoin network around the world on their energy use and found that…
