how do I disconnect this bulb??

[Blackpuddin]

Bathroom downlighter went on the blink, no problem thinks I, it'll just be one of those two-pin thingies, easy life.
Except no, it's one of these:



Having figured out how to yank it out of the ceiling I have no idea how to disconnect it without possibly blowing myself up.
All thoughts gratefully received.

Is that turquoise unit on top not a junction box? Different colour wire entering vs exiting? Can you pop the top of it off?

[Doofus]

It looks like the ring covered in paint needs to be unscrewed, and the bulb will just be plugged in inside the black housing.

Turn off the lighting circuit at the CU
Open the blue cover, and there will be screw or clamp connectors
Unscrew or unclamp the blue & brown wires
connect them into a wago or similar connector to make sure they are insulated. Or bend them away from each other and use electrical tape

[Blackpuddin]

What is a wago? Didn't understand much of that post. I can't stress strongly enough how much of an electrician I am not.
Here's two more pics, apols for crap quality but the iPhone camera has decided to join in the fun, iPhone is now constantly restarting itself grrr.

Need to see a picture of the other end (the end you see when the rest is up in the ceiling). It could well be a fixed lamp LED unit where you have to replace the entire thing.

Which is very simple, but you don’t seem very confident with electrics so caution.

Under the blue cover, the grey cable from the lighting circuit and the white cable to the lamp unit are joined either with screw terminals or click connectors. You likely need to disconnect the lamp unit and replace it, ensuring the power is off when you do so, at the consumer unit not just the light switch.

Does the silver sticker mention a bulb type? GU10, for example.

[Blackpuddin]

Right, by plucking up all my courage I twisted the bottom section which was caked with paint, managed to crack the paint seal OK and now I have this which looks a bit more hopeful, but I've got to go out now dammit

[Blackpuddin]

bloody camera aaargh

[miniman]

Yes that’s just a GU10 lamp, it will untwist at the black connector you can just see poking out from the main unit case. The white cover unclips from the lamp and you can clip onto the new one.

[Blackpuddin]

OK it's a GU10

I think you've broken it.

Just pull the bulb sideways out of the metal clip and slot a new one in by reversing the procedure.

Inevitably they are all LEDs now so may be a different light colour if the others are still incandescents.

Note GU10 bulbs come in two different flavours, from memory 35w and 50w, so check the wattage of this one to get an approximate match with the other ceiling lights.

LEDs will be 3w-5w.

If it was a yellowy-white colour you need warm-white, if a bright white, you need cool-white.

To put it back up, just hold the spring clips up against the cover as you push it in the hole

The old GU10 will have its specification marked somewhere along its base. Colour temp may be anything from 2700K (warm white) to 6000K (blue white). Trey to replace it with a similar colour temp.

Given the state of the overpaint and the cracked component, I’d be replacing the whole unit and probably all the others in the room.

[Blackpuddin]

Found the right 5w bulb in my jolly bag o’ bulbs, stuck it in and it illuminated in the correct manner. Scraped most of the excess paint off and shoved the main bit back into the ceiling using the springs. Just need to work out how to get the bulb holder bit back in place now. It’s just dangling at the moment. Knackered and it’s dark so I’ll try that in the morrow.
