Important notes
- Point-by-point distribution, glare, uniformity, vertical illuminance, and obstructions are outside this scalar estimate.
- Australian standards and project targets require current, task-specific review; this calculator does not declare compliance.
Formulas
- \(\displaystyle E_{\mathrm{avg}} = \frac{\Phi \times UF \times MF}{A}\)
- This is an average estimate, not a point-by-point photometric design.
Estimate average illuminance from lumens, area, utilisation, and maintenance assumptions.
Lumens to Lux Calculator is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
FAQs
Is the lux result uniform across the room?
No. The result is an average estimate and does not replace a point-by-point lighting design.
