Your responses are great. What I will do is to call for white epoxy paint on floor, walls, ceiling. Then install 4' long LED light strips mounted on the WALLS near the ceiling. One strip for each wall = four total. That should satisfy his light meter. I'm not joking about the light meter either. He will use his big body to cast a shadow on the light meter and then call for additional lighting. A light on each wall should eliminate any shadows unless he sticks his light meter where the sun don't shine.
