Should have said unmarked black(S) plural

There should be 2.They go together.

When you do this all the time you forget to make things plain enough.

Classic very common mistake.

All 3 reds go together with nothing else....put a terminal on them and tape it up.

The black with the red sleeve is your switched live and the unmarked black the neutral.

Connect the earth unless DI.

I am surprised another light isnt also in trouble

This is assuming your wiring is as it should be .
