For me all lights go off at 8pm then moonlights till 3am then total darkness.
I don't think you'd want the actinic lights on 24/7
Start with the actinic lights, then daylights then the reverse for night time. Daylights off then after a little bit then actinic lights off.
This is of course just my opinion but I think it's good to have a period of total darkness.
