There is also nothing to stop you daisy chaining the switched live from
the first lamp holder to the second rather than running a second
dedicated wire back to the JB. That way you only have the standard four
wires per JB.

When you say "daisy chaining the switched live", you mean connecting
live and neutral (and earth in this case) for the second light to the
three terminals on the first light? Or are the earth and neutral of the
second light handled differently?

And another thing. For the kitchen, which is three lights off one
switch, can I use the one junction box then daisy chain the second _and
third_ lights? I assume as it's a radial that I can - it's not like
daisy-chaining spurs on a ring circuit, but I'd love a quick confirm.
