Some good ideas, no winners, though.
No starters, just the ballasts. Used starters on the fish
tanks for years so I knew what to look for. sorry I didn't
mention it to start with.
3 of 4 are grounded using a 3-wire cord, the other has
the ground wire attached to a screw. Connection is good.
I could try a 12' ground rod through the floor, I guess.
They have Sylvania WORKSHOP F40 bulbs that are
always replaced in pairs except for a GE SHOPLIGHT
I just stuck in - it does the same thing.
Switch good - when turned on in warm weather they glow
dimly, then one or the other may come on.

Almost certainly indicates a faulty ground.

Well, if you do that, just make sure to wrap a #4 stranded copper around it
to ward off skin effect...

I have to say - I have never seen this happen. Have you measured your
voltage to ensure there's not a voltage problem? This would really only be
a consideration if they are all on the same lighting circuit though.

The ballasts may be overheating. is there air space between
the fixture and the ceiling?
Otherwise, the ballasts probably need replacement.

OR static electricity build up?? I have seen a restaurant owner turn on
the switch to his out side florescent lights, and then use a broom to
actually touch all of the tubes before they would come on. He gently
brushed them.
Buy a new ballast for one, install it and see if there is any change,
for the good, in that light. If so, change the ballasts. If not,
then it's probably a ground issue.
Replacing the fixtures, maybe? I bought seven 4-bulb fixtures (T-8
bulbs) for $35 a piece at Lowes. I didn't think that was a high
price. I got one "damaged" fixture (broken bulb only) for $10.
Check for damaged fixtures for discount purchasing.... at Home Depot,
also.

It's possible that your ground wire isn't actually connected to a
good solid ground. Easy to test and risky not to.

Run a ground wire to your pipes... maybe the ground is faulty..
You can check with a meter and see if hot and ground show voltage. If
they do your good.
