How this calculator works
Floor area is multiplied by the light level for the selected task. The maintenance factor allows for dirt and output loss over time. We round the fixture count up, since part of a fixture is no help.
Important limitationActual results depend on ceiling height, beam angle, wall reflectance, fixture spacing, shadows, color rendering, and local electrical requirements.
