On weekdays I work 9-6. I go home for my lunch breaks (usually get there around 1) and turn the lights on then. I leave them on when I go back to work...I assumed its not best to be turning the lights on/off multiple times a day. Depending how tired I am, between 10-11pm I turn out the regular lights and turn on the lunar lights, and I turn out the lunar lights when I go to bed (usually an hour or two after lunar lights go on).
On weekends it varies a bit. I turn the lights on not too long after I wake up (usually sleeping in on weekends...), and switch to lunar lights a bit later than on weekdays (midnight'ish), and lunar lights go off when I go to bed...
