Wattage is determined by circuit ampacity (ohm's law) But code say's you can only load a circuit to 80% of it's rating. Restaurants are based on 2 watts per sq. ft., offices on 3 1/2 watts. Title 24 requires 2 switch points per fixture for troffer lights, meaning two ballasts, so the light can be dimmed by using only one half of the fixture. Or, for recessed lighting, one half on one switch, the other half on the other switch.
