As part of a kitchen remodeling job, I am replacing a single overhead
fluorescent fixture with ~7 recessed cans and then a bunch of undercab
lights (either halogens or small fluor. boxes). Since the existing
fixture is part of a circuit that goes elsewhere in the house, I
calculated that all of those recessed lights would be too much for the
line. So I'm planning on running a new, dedicated 15A or 20A line.

Assuming the loads are within the capacity of the line (which I think
it is), the question is whether there is anything wrong with having
ALL of the lights -- overhead and undercab -- on this single circuit.
It seems OK to me but just checking.
