My garage has several shoplights with the older type of fluorescent dual

Both lamps went dead. I replaced only one of the lamps because it is
difficult for me to reach above my head. However, the new single lamp in
the fixture does not burn steady. It flickers mightily and also turns on
and off intermittently.

Does this mean the ballast is bad and that I should replace the fixture
with a more modern one?.

Thanks

You probably should have replaced both of the tubes...but I'd just
replace the whole thing with a more up-to-date unit.
