A TRUE GREEN LED that you use only in emergencies is fine. Don't leave it turned on when you are not in there, and don't let the light of you opening the door disturb the plants. If you must visit them at night, you will need to build a light-lock walkway and close the first door before opening the second.

But a green party light still interrupts teh dark cycle. I have tested this. It is not good.
