Still struggling with deciding how to update the ceiling lighting.

If I go for low volt downlighters, is it normal for each downlight
unit to have its own separate transformer?

If so I presume normal 1.0 or 1.5 mm2 cable can be daisy chained to
each outlet? & that then gives the flexibility to allow switching
between LV & HV units later?

Or am I misunderstanding something?

Any experiences of fitting & cabling downlighters would be much
appreciated.

TIA
