A room-level lumen estimate is a planning check, not a final luminaire schedule.
What to record
- Room dimensions and whether the area is whole-room or task-only.
- Target lux source and whether it is an assumption or project requirement.
- Fixture count, beam distribution, mounting height, and surface reflectance assumptions.
Calculator output is an estimating aid. Confirm project-specific requirements, products, electrical work, and compliance decisions with the responsible professional.
