Lighting circuit - spur from a spur/radial

[Makhaira]

Fitting a 58W fluorescent to my loft, and cable access is proving a nightmare. I can easily run from an existing rose, but it appears to be a spur itself, not part of the loop. Given that it's my house and I therefore know I won't continue to spur ad infinitum, any issue with taking a spur from that rose to feed the new light? Or am I being daft and this would just be the last looped rose?

Not the end of the world if it's not acceptable, just wanted to check before I started a lot of nugatory effort!

Also, if using blue/brown 3 core to run to a switch, what's the recognised sleeving to indicate a live and switched live? It'll only be a foot or two run along a loft timber, so source will be obvious.

I'd always rather ask and get it right than do half a job .

That's what I thought, cheers Nightglow. Presume I'm right in thinking that that rose would be the end of a looped in run and therefore I can run an extra light off it no worries? Not really meddled with lights much before, just sockets.

Haha, that's actually the way I was going to do it before I read up on how I *should* continue on from the last looped one.

I like to stick to the regs, even if what I'd be doing is electrically fine .
