Those claims are overly optimistic. First off, when I've bought CFLs for my house, I've found that the light equivalency is WAY low. It seems that what they compare to a 60 watt bulb is about the same amount of light that a 40w bulb puts out. And I've had to replace 2 bulbs in less than a year.

You must be buying those CDLs made in Elbonia. I have had all good results with mine. I only buy GE.
