LED ceiling light wiring

You will need to put the wires in a junction box and feed your light from that, assuming theres room in the ceiling above for the JB.

Something like this.

Also the light you've got looks metal with no earth connection, looks a bit cheap and naff to be honest.

Edit..having said that you probably have enough room in the fitting to connect the wires using connectors or wagos.

 

You connect to the same terminals as the pendant you are removing. The outer ones.
If you don’t understand why you should call a sparks.

 

There are junction boxes to replace the ceiling rose which have the same connections, the one @Ind spark has linked to is maintenance free type, but one can use a terminal block inside the light instead. The light you show is clearly not designed for the UK, in other countries they use the switch back box as a junction box, however our rules say "A circuit protective conductor shall be run to and terminated at each point in wiring" so even class II equipment should have a parking terminal for the earth to be terminated only "lamp holder having no exposed-conductive-parts and suspended" is allowed not to have an earth with installed equipment, non installed have different rules.

I look at the light, and wonder if you can cut a large hole in centre and simply leave the ceiling rose in place?

 

3rd line down on yellow sticker states that the fitting is indeed ‘double insulated’ / clearly the symbol we’re used to seeing that signifies this is different but, it is there in writing, plain for all to see

 

I'll take your word for it

 

Looks a piece of cheap tat, cannot see any conformity marks on it. If I bought it it would be going back or in the bin.

 

As above, send them back and get a refund.

l would not install them in my own house or for a customer.
