As far as your fictitious Professor Darklight is concerned I am quite
willing to disbelieve in his existence, or that his dark lights would

with his bulbs, then the street would have been darker, just as if
you shine cold radiation on an object it becomes colder.

The street would have been darker through the removal of the original
bulbs, not through any transmission of "dark light". In the same way
that Cloddy failed to realised that you cannot radiate a beam of
darkness, it is impossible to radiate a beam of "coldth".
