What Is Illuminance?
Illuminance refers to the amount of light falling on a surface. It measures how brightly an area is illuminated and is commonly expressed in lux or foot-candles.
This measurement is extremely important in offices, factories, hospitals, classrooms, photography studios, and outdoor lighting systems where proper illumination directly impacts visibility, safety, and productivity.
Common Illuminance Units
| Unit | Symbol | Description |
|---|---|---|
| Lux | lx | SI unit of illuminance |
| Foot-candle | fc | Imperial illuminance unit |
| Lumen per square meter | lm/m² | Equivalent to lux |
| Phot | ph | CGS illuminance unit |
| Nox | nx | Very small illuminance unit |
