To bych ti rekl ...  :-)
 tex.box[0].height
... To ale získáš jen výšku boxu, ne?
Co když ten hbox chceš vysázet Luou na nějakou šířku?
Na to budeš potřebovat node.hpack() (luatexref-t.pdf, s. 95).
\starttext
  \startluacode
    context(typesetters.hpack("Na to budeš potřebovat
'typesetters.hpack'"))
  \stopluacode
\stoptext
Now this is awesome. Never knew you could pass nodes directly to
context(). (Otoh it seems like you can’t pass the value of
typesetters.hpack() to node.write() anymore, even though it is
indicated in the comments.)

But now you need to set the width manually:
·······································································
\starttext
  \startluacode
    local hbox = typesetters.hpack"Hello World!"
    hbox.width = 2*hbox.width
    context"foo"
    context(hbox)
    context"bar"
  \stopluacode
\stoptext
