lux
Measures light intensity
Lux is the SI unit of illuminance, measuring how much light falls on a surface.
One lux equals one lumen per square meter.
The term appears in technical contexts like photography, architecture, and workplace safety standards: The office lighting measured 500 lux.
Direct sunlight can exceed 100,000 lux, while a full moon provides about 0.25 lux. (Capitalized Lux is a given name or brand name.)
