Installing an led strip light in a home office

[dps4]

Hey.. I’ve installed many lights at home before with no problems but I’ve got stuck installing a led light strip in my home office. The old light wasn’t a led light, it was some old spotlights.
It is on a loop wiring system with two blacks going into one neutral wire and two live wires, one insulated off in tape and the other going to the red live wire terminal. Earth wire is also present.

I then tried to wire in the new led light in the same way but just got a high pitched squealing noise from the driver unit and no light. I tried over and over to rewire it thinking I had a loose connection but nothing.

I randomly have another brand new led light so tried to install that instead. Same issue.

I then went out and bought a new switch and wondered if that was the problem, along with a pendant light fitting. Pendant light worked fine with the new switch and same wiring config, led light didn’t do a thing.. just squealed at me again.

I’m really lost.. any ideas?i
This is the light I have: https://lassola.co.uk/products/edge-flush-mount-ceiling-light-l-60-80-100-120cm
it’s the 100cm one so 20 watts.

And it’s the 3 colour variant. I bought a standard 1 way switch.

Any advice appreciated!

If the new pendant light worked and the new LED doesn't, what happens if you put a flex on the new LED light and put a plug on the other end of the flex (And plug it in)
Why did you change the switch?

Randomly swapping switches for no reason is unlikely to prove anything...

It is possible that the new light fitting is faulty...

As Richard suggested, connect it with a bit of flex to a standard plug..
Then see what it does directly plugged into a socket?

Two different fittings making this same noise, though. I'm wondering what the voltage is at this junction and also how it's wired, considering that taped off live.

Well spotted... I didn't notice the line saying...

"I randomly have another brand new led light so tried to install that instead. Same issue".
My excuse...

I am wondering if he has the wrong live....??

e.g. in the past I've seen people mess-up the loop-in, loop-out wiring so they end up with one or more lights wired in series with the new light fitting they were trying to replace!!

So end up with, "as you imply", far less than the expected 230v!!

I think this probably needs some dead continuity testing done from the CU to switch and light fitting to resolve fully?

..............But did you spot the line that said

along with a pendant light fitting. Pendant light worked fine with the new switch and same wiring config

To me that says he changed the light to his LED light, didn't work
Changed light to another LED light, didn't work

Went out bought new pendant light AND switch, both worked.

I’ll try putting it into a pendant and see.
I swapped the switch a I couldn’t remember if I’d bought the dimmable one and read that some led lights are not compatible with old switches. It wasn’t the dimmable version. I think (98% sure I tried both live wires in the end) but don’t think I did this with both lights

Quick read of the spec says it's only rated for 240v , I suspect it might have died, as UK voltage can be as high as 253V

It is only dimmer switches that have to be compatible with dimmable LED lights..
Manual switches are no problem..
But your light states if you did have a dimmable fitting it uses a small remote control, not a dimmer switch..

You haven't had it connected via a traditional dimmer switch have you?

Basically you are using the wrong, testing method..
10 or 15minutes of dead testing with a suitable continuity tester, will prove the physical wiring connections and polarity etc..

If you have proved the wiring and switch you then the fault is related to the fitting itself.

Dead testing is far safer than swapping and then trying various combinations of connecting live wires..
