11×12 room:
how many lights?

4–16fixtures A 11×12 ft room is 132 square feet. How many lights it needs depends entirely on what happens in it — a kitchen is lit to roughly twice the level of a bedroom, so the same footprint ranges from 4 to 16 fixtures at 800 lumens each.

The footprint does not decide the count. The target illuminance does, and that is set by what the room is for.
