Adding two extra loft lights to existing light

[Sleebagz]

If I've understood you correctly, you'll probably have 2 cables coming out of the JB, one goes to the repositioned (roughly) central light which then daisy chains to an extra one and the second cable goes in the opposite direction to the final fitting.
In the interests of being condescending, don't forget some cable clips.

I was thinking 3 separate cables out the junction box to the three fittings, but what you suggest makes sense actually: one cable out the JB to the repositioned (central) light and then running one daisy chain off the central light to one end of the loft. Then a second wire out the juncction box to the final fitting at the opposite end.

I don’t suppose there’s any advantage to running 3 separate cables out to the lights from JB? May as well daisy chain one of them if possible?

And yes I’ll make sure everything is clipped to the wooden beams and secure
