Pick the spot
Decide where the base cone will stand. It is 4.7 in (120 mm) across and the cord has to reach an outlet. Mark the floor.
Find the point on the ceiling directly above the mark. Hang a weighted string from the ceiling, or use your phone’s level app held against the cable once it is up. Keep the ceiling point at least 3 in from any wall so the 3.1 in (80 mm) light cones clear it. Mark the ceiling.
