Downlight Wiring

[wassupjg]

Hi guys, super basic question:

For a room layout like this, with my understanding that a lighting circuit downlight radial goes from one point to the next (whereas a socket radial can spur off in multiple directions), would this be acceptable, with the first downlight spurring off to feed two lines of downlights, or would it be "overloading" the first downlight, with 3 tails going in?

Would it be better to use extra cable to feed the 1st downlight on the left and then follow a true radial?

Or a junction box (hager j804) close to the feed splitting into the 2 legs? Maybe avoid a junction box as it's an unnecessary extra junction and therefore potential point of failure?

Cheers!

All methods are fine. Your first instance with three cables to the first light is going to need a separate junction box as most downlights accept a maximum of two cables. Some only accept one so this is a factor factor in all your examples.

An extra joint box isn’t a massive issue… use a wago box, with proper wagos. Nice and small will fit up through downlight hole.

Wago box should never need to be checked… but good idea to leave it accessible. (Enough cable to pull out the hole if needed)
