Well actually that proves that the study was dumb as shit in the first place. They are saying that incandescent bulbs loose 7% of their brightness over a time period of 2,000 hours. Then they state that the CFL are tested over a time period of 10,000 hours and lost up to 22% of brightness of those that actually lasted the 10,000. Well if you multiply 7% by 5 you get 35%. So didn't they really just prove that the high quality bulbs are even MORE worth it than incandescents?

Study Casts Dim Light on Energy-Efficient Bulbs Thursday, November 19, 2009 They're billed as energy-efficient, but compact fluorescent bulbs are getting a dim review in a new study. The study, published in Engineering and Technology magazine, shows the energy-efficient light bulbs lose on average 22 percent of their brightness over their lifetime, the BBC reports. Compact fluorescents reduce energy consumption by up to 80 percent compared to traditional bulbs. But the study Rating: 5
