Which ever is easier.
BUT
Bear in mind most modern light fittings only just have enough room for one cable.
Wago connectors are better than junction boxes
You should use 1mm twin and earth
You must connect the earths (Even if the light does not need it today, it may do next year)
Take clear in focus pictures before you do anything, and check that they are clear and in focus
Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.
The HT5910 is about the cheapest multi-function tester I can find at £61.72, and it does not have a low ohm range, and the loop test resolution is only 0.1 ohm. Most testers are 4 times that price.
It is all well and good saying you would not hit a nail with a shoe, but I have used all sorts including a brick and a shoe in the past, so you need to decide if you feel confident you can do the job.
The problem for the electrician is he must follow the rule book, so cables buried in a wall need RCD protection, it does not matter if 25 years ago we did not need it, any new cable today does, so what seems a really easy job, the "Just Job" ends up needing a lot more doing for him to sign his minor works certificate.
So we are all temped to DIY, not to save on the job, but so we can cut corners.
One can debate until the cows come home, as to if required, but back in the 90's when RCD's were not required, I fitted them in my own home to protect my son, (He had just passed his RAE amateur radio exam) and I wanted to protect him.
As said both methods are permitted, I looked at my own house, and access was the problem, so I have uplighters, cabinet lights etc. To add to the existing lights.
I am debating how to do kitchen lights, and it seems the way around the problem is likely lighting track, not that I really want lighting track, but it is a way to get cables across my ceiling without it looking like an after thought, even though it is.
The traditional way was the fluorescent fitting, it was not we wanted the fluorescent, but the long design allowed us to get light away from where the wires are.
The original light used 1.5 mm earth twin cable. I already bought this. Can I use it (I understand that it might be an over kill, waste of money and copper), or is it not safe to use the 1.5 mm?

If gloom had a voice, it would be me.
