It was not clear to me what you are after, so you want the pattern to be:

^led@(?:[1-9a-f]|1[0-9a-f]|2[0-4])$

So the range of the unit@ string is controlled via the pattern
orthogonal to reg,
the range of the reg property explicitly via minimum/maximum which are decimal,
despite the fact that the reg itself can be a hex value, which is
preferred for readability
I suppose.

Kind regards,
