14×18 room:
how many lights?

6–24fixtures A 14×18 ft room is 252 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 6 to 24 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.
