Stuck flourescent tube

Has anyone any suggestions? The tube is on quite a high ceiling, so not the easiest place to get at. The 2 pins on the tube won't come out of the socket at either end.

Yes, we have replaced the starter so it clearly is the tube that is the problem.

Would a squirt of WD40 be safe? (I never remember whether WD40 conducts or insulates).

Many thanks in advance

David

You do realise that the tube has to be rotated 90 degrees to enable the pins to be released?

I have two flourescent tubes in this house,the older of the two the pins just pop out by pulling the ends apart,the newer one requires rotating by 90 degrees.It caught me out the first time I had to change the tube.

You can't beat some good 'ol 'njineerin' to solve just about any snag!!!!!!

I'll never forget the day the SENGO was "freeing up" his car's brake caliper piston using a nitrogen bottle in the hanger. Cept he forgot to use a pressure regulator.

Worked a treat! Piston ejected from the caliper immediately, impacting the diagonally opposite corner of the hangar, leading to a myriad of us maintainer goons bailing out from several aircraft going "WTFWT???" thinking something had exploded!

We didn't laugh ... much .... when we found out!!!!!!

I have just had the same problem within this past week. I had to pull the 2 ends apart to get the diffuser off, then rotate the tube to get the 2 pins to come out. And then the fun started! I searched on the web for the correct replacement. Nothing. Everything I did find kept harking back to T8 or T12 fittings etc. I looked at the old tube and it had R8xxx stamped on it. Looked up R8xxx and again, nothing. The light fitting had a Homebase model number on it so I looked for that, in the hope it would be give me a clue. Nothing. Not even recognised on the Homebase web site. To make things worse, I noticed a lot of the tubes on offer featured what looked like a metallic strip along the length of the tube which, according to the blurb, made the tube a self-starter. Worrying; my tube had neither a strip nor a starter!
Eventually, I took a chance and went to the Homebase store and there was another bloke, of a similar age to me, scratching his head, trying to figure out what he was going to buy. Eventually, we both chose tubes marked "T8". I was full of misgivings but I chose the T8 as it was the correct length but the diameter of the tube was much smaller than the original. Having got an assurance from the guy on the checkout that if it didn't fit, I could bring it back no questions.
It went in the fitting easily and worked a treat. The diameter of the tube was quite a bot smaller than the original but it still hasn't fallen out!

clean tube, when dry cover in parcel tape then . . .

Did this with a car window and a 3x2 house window. No mess.

Kelvin:
The number that comes with the T is used to denote the diameter of the fluorescent tube. Since the measurements come in eights of an inch, the T8 has an inch of diameter while a T12 comes in 1.5 inches. The narrower your choice of fluorescent lamp is, the more efficient its energy output would be.
Don't know your application but when I rejigged our garage I changed the single 40 year old tube for a couple of quad LED spots.

I n the kitchen we had a pair of tubes recessed into the ceiling in the kitchen. Had we stayed I would have used the recess and gone for LED there too.

Recently replaced two garage fluorescent fittings with LED strips.

Same physical size
No wiring changes
More light with less power
Instant start
Not affected by low temps
No further tube replacements

What's not to like?

You can get LEDs to replace fluorescent tubes now, even using the same fittings.

That’s what my tame electrician did for me last week with two fittings, and like SA1234 posted above they are no longer affected by cold temperatures in the loft where they are fitted.

I've replaced all the fluorescent tubes in my hangar and a couple at the house with LED tubes. I get the ones that work without the ballast and rewire the fixture. They are awesome.



At the end of this video is another view of said lights.

Edited again because the editor works horribly on the phone. On the PC it is an upgrade to poorly.

WD40 drives out moisture, and is safe on electrics, but keep the fitting switched off overnight after spraying and donít drown it.

Main thing is be bloody careful up high step ladders, if your stated age is real.

At my age the biggest problem is close working above eye level, impossible with bifocals. I keep a pair of readers handy.

How will it be any use, knowing the OP's problem is not being able to get the old tube out?

Around here I'd have to get a Federal permit, environmental impact study, notify the neighbors to evacuate, and give 72 hours notice.

There's no place now to dispose of fluorescent tubes. (I smash them up inside double plastic bags and put them in my neighbors' bin, but don't tell anyone.)

Thanks everyone. Yes, my age is as shown here, I'm afraid, but my son will be going up the stepladder.
