I don't think so, but those posts that hold the lamp can be replaced.
While you are at it, take the fixture down, replace the lamp holders,
remove the ballast and put an LED tube in there.
You'll be happy you did and odds are, you'll never replace that tube again.
Depending on your age, you have a very good chance of that tube
outlasting yourself. Or, you may move before the tube gives up.
I replaced 4 tubes in a plant light with LED tubes. Before this,
I'd replaced the florescents more than once. They would noticeably dim
after a few years. I've had the LEDs in there for about 10 years now.
No degradation, and the color temperature is very pleasing.
I recently replaced all my outdoor house lighting. There are no bulbs
at all. The LED is built in to the fixture. They expect the light
to last as long as the fixture.
I replaced my kitchen can light fixtures. I had LED bulbs in there,
but the new ones were even better. Again, no bulb, but also no
opening into the can. Each fixture had a switch in it so you
could pick the color temperature you wanted. (5 different colors
to choose from.)
LEDs are not only more efficient and last longer, they are way more
I think what you're after is called conductive grease. Something

The makers of that stuff are pretty proud of it price wise.
You don't want dielectric grease which is non conductive.
ACtually, I think dielectric grease is what you would want to use. It's
what's used in auto lamp holders for example. Conductive grease would
create a current path. Dielectric grease works by keeping it lubricated
so it won't corrode, but it gets easily pressed out of the way of the
contact point so a good contact is made.
Bit I've yet to see a tube fixture that needed it. I'd suspect if you
put the bulb in correctly and twist, it will seat. Sometimes they can
be tricky, not sure grease will help. And agree that if it were my fixture
I'd be looking at a new LED fixture as the first choice, or maybe a
retrofit if it can't be changed easily. They don't cost much, sure look
and work a lot better and use less electricity.
Temptation would've gotten the best of me if I was doing it for
myself. I would have tried the WD-40 or powdered graphite if I really
thought it was needed. Then I would have waited a couple hours to let
things settle out.
I lot depends on the fixture itself. If it was cheap to begin with,
buying a new LED ready to go is probably right but for the same amount
of work you can just hot wire the tombstones, remove the ballast and
use the direct wire LED. That is certainly a better idea if this is
some kind of designer fixture you really like. They are supposed to be
good for 10,000 hours or more so that is. quite a number of years if
you are only using it a few hours a day. The old school F-40s in our
walk in closet are 20+ years old. I have never replaced them but they
only get used minutes a day.
Also pay attention to the color. LEDs come anything from a warm 2700k
to an arc light "stalag 17" 6000k maybe even "hotter".
You don't know my wife. I think she spent $100 on the one in our
closet in the late 90s. It may not have actually cost her that much
but that was the MSRP. She worked for in interior design place at the
time. I wasn't involved. I just put it up. It is an industrial quality
ballast and good tombstones. Not the junk you got in $20-30 "shop

seems logical it could happen.
I converted to LED tubes - disconnected the ballast and discarded. It turn
