If I remember, I try to turn my moonlights on 1/2 hour or so before I go to bed. They do run and spaz a bit when you hit the light, mine do at any noise. Anyway, I'm training them to know that when the blue light comes on, find your hiding spot quick because the lights are going dark soon. Now, I hit it and they all go flat and scurry to their spots and then I shut it completely off before I head to bed. If I leave the moonlights on too long, they all just get back up and start chasing each other around, again just like it's day, so it doesn't work to be on all night for me. I like it off at night anyway.
