Light pendant

[JKA]

Hello
A downstairs 5 bulb candelabra light has developed a fault that I am unable to identify - for some unknown reason, when I replaced the bulbs (to LED) the light now appears to be in series (ie each bulb getting dimmer!). No wiring has been altered. I swapped in another fitting that I know is working fine, and the same happened. I fitted the original elsewhere in the house and that, too, is working as it should.
Any ideas as to what may have caused this this, and how I might go about fixing it?
Thanks

What type and voltage are the original lamps.

Wired in series?.. Do they all stop working if you take one lamp out?
If less than 5 in any combination will still illuminate then they are definitely wired in parrallel...

As has been asked.. are these 230v or 12v lamp?
I am guessing probably a 12v transformer -vs- LED driver non-compatibility issue?

Thanks for questions:

1. Original bulbs where 40w filament
2. If I take out 1 LED, they all get brighter (take out 2, get brighter still and so on)
3. If I use only 1 LED bulb, it's not very brighter (use it in another fitting and it's full brightness)
4. If I use only 1 filament bulb, it doesn't work...

Is the new light connected correctly.

sounds like induced voltage , rather than switched live

There hasn't been any alteration to the connections...
I'm not sure I know what induced voltage is - and what has caused this to happen?

Induced voltage is created when a live cable runs parallel to another cable

It often creates enough voltage to dimly light a led light - but never enough to light a halogen bulb

So you’ve just swapped the light bulbs?

This particular pendant has been in place for years - but always 'got through' bulbs at a much quicker rate than any other light fitting in the house. Eventually the last filament bulb blew about 2 months ago, and we just used lamps instead. Decided last weekend to replace the bulbs (and could only get LED), and that's when I noticed the issue. I managed to get some replacement filament bulbs online (to check it wasn't an LED issue) and saw that they weren't working at all.
What can I do about the induced voltage (apart from lifting floorboards!)?

dont go lifting floorboards

can you post a photo of a “good” bulb?

dimmer or normal switch ?
