I try to mimic a daytime light in a regular room by lighting the ceiling above the tank for 24 hours - so not too bright - it seems to work just fine.
I turn the lights off at night after the first 5 days and keep them on only during the day. That is the time I also add the sponge filter - just easy for me to remember.
