This is the time of year we get a lot of these questions. Most of them
are a result of cold temps. Standard fixtures just will not fire off when
cold. A poor ground just makes it worse.
Make sure the metal part of the fixture is really grounded. If not then
you need either a new cold rated ballast or a new fixture. If you have a
cheap fixture, just replace the whole thing.
Of course it could have been just something else going out, like a
switch, wire or the ballast.
