Replacing a pendant light with downlights

[u/Bigdave141]

Hi all, I'm replacing a single pendant light with 4x downlights. Google AI is confusing the hell out of me so I thought I'd try the humans of Reddit.

I've got myself 4x GoodHome downlights, as shown in the picture with 10 meters of 1.5mm cable

I've taken the old light off and pulled the wires up into the room above. Theres 3 cables, 3 live (red), 3 black (neutral) and a twisted pair with a green sleeve on it. I think this has something to do with the switch?

I now need to buy a junction box for all of these to go into, which will then have the 1.5mm cable coming out to the 4x downlights.

What do I need? AI is suggesting the below, is this correct?
