What is the correct way to spur off a ceiling rose on a normal ring circuit?

2.5 cable, spurring from a rose on a normal ring?
Using such terminology, I must admit, I'm hoping OP has some serious engineering skills and isn't taking the pee.

LOL yeah will be wrestling them conductors in with that gauge. Ring?

Looking at that rose photo, I never can understand why people 'double up' without using available terminals! Look at the damaged screwheads, 2 completely perfect!!

A follow-on question has occurred to me: do I need to run the same gauge wire as is used in the ring (2.5mm?) to each of the light fittings? I'm guessing maybe yes because no fuse is involved anywhere but it's going to be a fiddle to get all the wires into my junction box (reminds me of a certain film: "We're gonna need a bigger junction box.").

No lighting is wired in 1.5mm2 twin and earth and make sure you sleeve the earth conductor with green and yellow sleeveing

With some of the LED drivers these days it is better to use 1mm instead of 1.5mm as they are a pain to get the conductor wrangled in to the terminals.

Well, I once built a computer from the level of individual resistors and capacitors but, as I said, I am not familiar with domestic wiring regs. Hence my question, based on the knowledge that these higher voltages and currents can be dangerous. But, yes, as soon as I'd made the post and gone in the loft to do the actual work, I did realise that it was a bit silly. One glance at 2.5mm cable made me realise that I'd have to be powering a garden full of halogen lights for that to be necessary. On closer inspection, the lighting ring is indeed 1.5mm.

Its just the wrong terminology.

A "ring" is normally used with sockets, where a twin and earth cable leaves the fuseboard, drops off at every socket on the circuit with a "one in, one out" and returns to the fuseboard, hence a ring circuit.

A lighting circuit, and most others are "radial" like the branches of a tree.

With low energy lamps, 1.0mm is much more common now
