the grid graphic looks very current-military to Moore's BSG to me, but then again, it also looks like the bridge graphic in TMP of the vger weapons encircling the earth.
It is hard to tell about whether the set is lit or not, because lots of times you will overlight a set and then stop down to get greater depth of field ... that happens a lot on horror pics to get depth in night scenes (which is why when you see a behind the scenes of NIGHT MARE ON ELM sequels that it seems so bright on set compared to the final film), and would be useful on a big bridge set if you needed depth of field and couldn't use a wide lens.
The idea of having it bright some of the time, then going dark for battle conditions (a la TFF) is fine by me; TOS did that as well, but was even more gutsy (the BOT shot where ALL the lights are off except the blinker at the back by the lift and the helm light -- both red -- is very exciting visually, even now.
