24×24 room:
how many lights?

16–49fixtures A 24×24 ft room is 576 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 16 to 49 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.
