In my basement utility / laundry area I have a half dozen fluorescent fixtures. Two fixtures have newer electronic ballasts and 4 have magnetic ballasts. It seems the lamps last forever with the mag ballasts but not so long with the newer electronic ballasts. The lamps are 1970s vintage F40T12, when I bought the new fixtures I was careful to get (and had a hard time finding) fixtures that could use my old lamps.
Just from common sense it seems it would be harder on the lamps, since they turn on instantly with the newer ballasts, but are “ramped up” with the magnetic ballasts.
