About these units
Lux (lx)
- Definition
- The lux (lx) is the SI unit of illuminance, equal to one lumen per square meter — a measure of how much light falls on a surface.
- History
- It was adopted as an SI unit in 1960, derived from the lumen and the meter.
- Current use
- Lux is used in lighting design, photography, agriculture (grow-light intensity), and workplace health and safety standards.
Nox (nx)
- Definition
- A nox (nx) is a non-SI unit of illuminance equal to one millilux (0.001 lux), intended for very dim conditions.
- History
- It was proposed in the early 20th century for measuring nighttime light levels but was never officially standardised.
- Current use
- Nox is largely historical; modern low-light measurements use millilux or microlux instead.
