I’m replacing a halogen spot light with a LED spotlight in the bedroom. There is only one lighting cable going to the existing fitting, which is connected by a terminal strip, so I can easily see brown to brown (live) and blue to blue (neutral). On the new fitting I have live and neutral, In and Out as follows > (L,E,N) In and then (N,E,L) Out. Does the in-coming power supply both go to the In connection on the light fitting or both to the Out connection or one in each (and if so, which way round)?
