Lighting Lux Calculator
Calculate the number of luminaires required to achieve target illumination levels using the lumen method. Includes room type presets, maintenance factors, and spacing recommendations.
Room Dimensions
Lighting Requirements
Standard requirement: 500 lux
Efficacy: 100 lm/W
Enter room dimensions and lighting requirements to calculate
Notes:
- Calculations use the Lumen Method (CIE recommendations)
- Room Index affects light distribution efficiency
- Higher reflectance surfaces improve utilization
- Consider glare, uniformity, and color rendering for detailed design
- Emergency lighting may require additional fixtures
