How do I take this off?

[househuntinginthesouth]

The light shade thingy...it's supposed to unscrew off but it's stuck on there, I've been trying for absolutely ages and I think it must've melted and got stuck to the other piece. Anyone know how else I can get this off...perhaps cut it off safely...

you mean the white collar? I'm not sure it does. I can't see a join with the "base" above.

Does the lamp hang from a flex, or is it rigid to the ceiling?

Is the collar white plastic, with a dark brown fitting inside? Plastic lampholders often (used to) jam together from the heat of older incandescent lamps. Modern LEDs run much cooler so I am hoping this problem will go away. You can try gripping the parts while wearing rubber gloves of the washing-up, not surgical, type. These give a better grip.

I think it may be a screw in (Edion) fitting so you must be careful not to put your finger inside. Some parts of lighting fittings are live even when the wall switch is "off"

btw you can lubricate plastic parts with silicone furniture polish sprays (not cleaners). It will be hard to get any reach the thread, though. As the sprays also contain water you have to turn off the circuit power first, and not touch until it is dry.

@PigletJohn I'm not sure what it's called. Normally I'd be able to remove it to change the lightshade and then screw the white bit back on to hold the light shade in place.

(We use the bayonet lightbulb.)

Also yes it's got the black but inside, annoyingly the top bit unscrews easily but there is wires underneath which is why I've given up for the meantime. I think what you've said has happened, what happens with the old style lights. Is this someone I can sort out or will I have to call someone out?

does it hang from a flex? how long?

How many screwdrivers are in your set?

I have no idea what you mean?
It's just a small piece of plastic that normally twists off.

I had one of these which stuck and I got it off by breaking it with wire cutters. I turned off the power at the circuit board first, then snipped the plastic fitting with the cutters until it broke off. You can buy replacements cheaply in DIY shops.

I mean, is it a pendant fitting, which hangs from the ceiling on a flex?

Ah yes.
It's like that.
Photo I've attached...top arrow is the bit that does screw off, bottom arrow is the bit I'm trying to screw off.

I melted ours on by using bulbs that got too hot. Switched to led now after I noticed they all looked melted.

if you are competent to do small electrical repairs, and know how to isolate the electricity at the consumer unit, and have an extra-small electricians screwdriver, you can fit a replacemement bulbholder yourself, without opening the ceiling rose.

You need a sturdy stepladder that will not wobble. you are more likely to be injured falling off than having an electric shock on this sort of job.

Do not rely on a "neon screwdriver" type of electric tester. The instrurments are best hurled into a bin with great force.

btw if you can hold the black ring round the "waist" of the bulbholder, do that when trying to unscrew the collar. It may have two nibs to make it easier to grip.

you can buy a new bulbholder, but as you see from my link, a replacement pendant set is so cheap you may as well do that. When you take it apart you will see how the wires and cord are fitted to resist pulling out by weight, and it will give you practice at undoing, and not losing, the tiny screws.
