I have a ceiling fan with a light kit (Casablanca) and the light bulbs are
very hard to remove. Standard base, small globe bulb. I've been using GE
brand bulbs. The last time it was so hard to unscrew that I actually twisted
the bulb socket right out, and they are about impossible to reassemble due
to the location of the locknut. Since the wiring at the bulb sockets was
hard as a rock, I replaced the light kit with a Hunter that was identical.
Since the bulbs were still very difficult to remove, I looked at the bulbs
themselves, and they appear to have a rough surface on the threads, I
suppose to keep them from vibrating out by themselves. My wife doesn't dare
change a bulb for fear it will break in her hand before coming out. I've
tried installing them loosely, but don't want to cause an arc situation,
So I'm looking for any suggestions on how other people have dealt with this.
I'm having a similar problem with a hanging kitchen table fixture.
Ceramic tubular decorations with the sockets deep inside... turn the
bulb, the socket turns... holding the nut on the outside doesn't stop
the rotation. Can't get two hands up inside to hold socket and bulb

There is a product used to lube the bulb/socket threads. I got
it a Menards. It's basically a silicon-base grease ... Seems to
works, however, I don't have too much experience with it. I
have also used the stuff in theatre lighting units where the
heat is very high 500 - 1000 watts ... not on the electrical
contacts, but on the adjustment screws which move the bulb
carrage closer to and further from the reflector. It does seem
to work pretty good for this application even though it was not
meant for it.
I was visiting a friend who was fighting with a bulb in one of those
fixtures. I thought he was joking until I gave it a try. I suggested
spraying some silicone lube in there. He did and the bulb came right
out again. Of course that was 2 minutes later. I'd think the
silicone grease would last longer. They sell some silicone grease at
Radio Shack for heat conductivity between a power transistor and
heatsink. I'd think that would work if you cant find the others.
This must be what they call PROGRESS (making life easier for mankind).
It used to be simple to change a lightbulb....... not no more!!!
If you are using bulbs with aluminum threaded bases, try finding ones with brass
bases. Those aluminum bases gall like crazy.

"If you can keep smiling when things go wrong, you've thought of someone to

The proper lube to use would be "dielectric grease" which will add the
needed lubricant to ease a bulb out after it's blown out, improve
connectivity, and aid in resisting corrosion.
Hope this helps,
