Lumens for
800 square feet
21,439lm ambient A 800 sq ft room (74.3 m²) needs roughly 21,439 lumens as a living room, rising to about 37,663 lumens as a kitchen and 38,710 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 800 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 800 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.
