How to Change a Lightbulb

This is a serious question, not a "how many ___s does it take" joke. I don't know how to research it.

The floodlight bulbs in my ceiling - 2-1/2 stories up - are being changed when we paint. They had not been changed once in the 20 years the house has been up, because they were up too high. The painters will be using ladders - not scaffolding.
Yesterday I tried to replace 2 bulbs of the same generation (but not as high), and both pulled off, leaving the metal base in the socket. Meaning, the highhat had to be dissassembled to remove the remainder of the bulb.

This was an OK job on a small stepladder, but not one I want to do 25 feet up on a ladder.

Any suggestions on making sure the bulbs screw off intact?

Be careful. If it does break you can cut a potato in half and push it onto the broken base and twist it out. This will work on one of those poles too.

No guarantees with taking the old bulbs out - but when re-installing, smear a bit of petroleum jelly on the threads and when you need to change the bulbs in 2027, they should come out without protest.

Or use nose oil. You always have it with you.

Don't know where I heard this, but somewhere I learned to rub the bulb's threads across the bridge of your nose before installing a bulb. The oil in your skin lubricates them. I do it subconciously now and it still cracks my wife up EVERY time she sees me do it. Better check a mirror when you're done. Some bulbs leave dark lines on my nose.

I have always used plyers when they break off....never had to disassemble a fixture yet....and some penetratin oil....turn off the circuit first.

I like the potatoe idea, never heard that one before. I suggest buying 130 v bulbs and oversizing them and using a dimmer to promote long life. If you seldom use them this will not be worth doing.

I've heard of using a potato, but I didn't think that was an option here as they twisted off cleanly - no jagged pieces and nothing sticking up.

I think I'll try a little squirt of penetrating oil for the future. I suppose it can't hurt.

For the replacements, I like the 130V idea, with a dimmer. That makes a lot of sense.

Thanks all.

I just did a search and found this link. I like the broom handle idea too.

I usually use needle-nose pliers and grab and slightly twist a portion of the lip of the bulb's metal base. That area usually allows enough purchase to use the pliers to rotate the socket out of the receptacle.

Note: Um, first make sure that the power is turned off. Here's a man who overlooked that fine point:

Don't change them. If you do they will just burn out again.

The 130V bulbs are a good choice for longevity. They don't need a dimmer for long life, as the filaments are already too heavy for the applied voltage and the light output is reduced.

I've only seen these bulbs in the standard size..........not the typical floodlight that is common in ceiling high hat fixtures.

I'll vote for dimmers, I have them on most of my Incandescent type bulbs.
Since they ramp up and down, the death rate is almost zero.
As compared to one area with a regular switch that goes through them constantly.

NOTE if you get the new CFs, you cannot (generally) use dimmers.

They do now make CFs that look like floods.
When they first come on, they are dim, give them 5 minutes, and the are as bright as regulars, and I like the color better. Supposedly they last much longer than regular bulbs.

Removing the old one, I like Needle nose, DO TURN OFF POWER.
I use a little silicon spray on the base generally.

I am not sure that is a good idea. It might burn off from the heat. The silicone sounds more promising. Maybe a LITTLE never seize?

Why not use some dielectric grease? A super fine coating ought to do.
