I have a few light fixtures around the house where there are multiple sockets per fixture - 4 sockets/fixture in the kitchen, dining room, bathroom ceiling light fixtures. I began the process of converting these over to using all CFL bulbs, but wanted to use up the supply of incandescent (Edison) bulbs I previously had. Thus, in some fixtures, there were 2 CFLs and 2 Edison bulbs.
I have noticed that when bulbs have failed in those fixtures, it was usually the Edison bulbs. Is there a particular reason(s) why having CFLs and Edison bulbs in the same fixture might be bad?
Assume that each bulb is rated for the same actual wattage.
