The quantity is always rounded up to the next whole fixture, because part of a luminaire cannot be installed.
The two factors reduce the light we can count on. The utilization factor accounts for light that never reaches the working plane; the maintenance factor keeps the design valid as output slowly drops over the fixture's life. Together they raise the lumens the design must deliver on day one.
This calculator provides a preliminary lighting quantity estimate only. Final fixture quantity and layout may vary depending on beam angle, ceiling height, room geometry, surface reflectance, photometric data, spacing requirements, and project-specific conditions.
