study indicates CFL lumen loss ...
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?
