Screw Off
 

Can someone explain why the light bulbs in my basement bathroom ceiling light keep unscrewing themselves? The vent fan is an inline and not even in the room so I don't think vibration could be a factor.

Jokes are welcome.

Haunted ... I'd move ..

probably because you didn't have the correct amount of Italians screw it in.
5 is the recommended quantity if you intend on remedying your predicament.

The magnetic field from the current in the wires.
The current surge upon turning on the lights could be turning ever so slightly.

Could be that the expansion of the bulb threads when hot then the cool air passing by the bulb is causing a large clearance between the bulb threads and socket threads thus causing the bulb to loosen.

HA! Awesome.

One to hold the bulb and four to turn the house.

Could be. It uses a smaller base and the threads aren't that precise.

perhaps your drinking something Australian

setting up a quantum exclusion.

Foot steps upstairs could do it too

Check the wattage of the bulb/lamp compared to recommended. If your wattage is too high it could be expanding the metal in the socket particularly if the lamp base and the socket are dissimilar metal. Couple that with slight spring tension on the positive contact of the socket it could be pushing the lamp out slightly during use and then after use the metals shrink eventually you lose contact with the positive contact.

^ very valid idea. I bet it is a combination of everyones suggestions.

Not a joke.

then again when you over torque something
it causes it to loosen up at least in engines
that is.... might be a factor ...or your
home is built on top of a fault line

When you install it try turning it to the right next time! :)

I would put it in , turn it on , let it get hot , then tighten it snug again (to the right!) . See what happens.

If that doesn't work , hire the 5 Italians.

write SANTA a Letter LOL

Jeff...
ask Paul about the owl figurines

I know about those. Whoa

Didn't he tell the story in front of both of us?

I'll check on the specs of the light when I get home.

I am a 3rd gen Italian electrician. If I got my father his brother and two of his uncles we could handle the job. It would cost you close to 1000 dollars to install the lamp

Probably, but there was a lot of bourbon flowing that night....

Got Kids?

Could have been on the ferry.

You think they know how to open a light fixture???

I think you got a batch of bad electricity

You never know.....but I was thinking more along the line of a whole lot of running around.....vibrating it loose

Did you remember to use the locktite?

after you break the bulb shove a potato on there
and then you can turn it

ha ha ha the nuerons misfired lol

:hidin:

it's called bolt stretch...that's why every grade bolt has a torque value...then there are single use stretch bolts.. subject of discussion for another day.

bulbs will loosten over time from repeated heating and cooling... location and surroundings have alot to do with it..... eventualy to the point where the contacts corrode and the light no longer functions..

Could have used the "5 Californians" version.

1 person screws in the lightbulb and the other four "share the experience"! :biglaugh:

When you sleep, does the house rotate clockwise or counterclockwise as seen from above. Mine goes clockwise, so the bulbs in the ceiling get tighter, and those in the table lamps eventually fall out.

So this weekend my 3 year old hands me the glass part of a bulb he just picked up off the floor. I look up and one of the recessed R20 Halogena's just broke cleanly at the base and fell to the floor. Good thing it hit the rug and didn't break.

Clearly, your house is haunted.

One of the weirdest things I've seen on a job site was hinge pins working their way out of the hinge without the door actually being moved.

That would be a slick trick if you could do it on demand.
