Lumens for
550 square feet
15,706lm ambient A 550 sq ft room (51.1 m²) needs roughly 15,706 lumens as a living room, rising to about 26,988 lumens as a kitchen and 27,770 lumens as a home office.
A lumen total is a budget, not a layout. It says nothing about whether the floor is even, which is the part the contour sheets on the footprint pages settle.

Fixture counts assume a roughly square room at an 8 ft ceiling; a long, narrow 550 sq ft room has a lower room index and needs more.

AdjacentTake it to a real footprint
Square footage is where a lighting question starts and never where it ends: two 550 sq ft rooms with different proportions have different room indices and different counts. Pick the actual dimensions on the footprint index and the sheet comes with contours drawn.
