Key Terminology
- Lumen per square meter (lm/m²)
- An SI derived unit of illuminance defined as one lumen of luminous flux uniformly incident on one square meter.
- Candela steradian per square meter (cd·sr·m⁻²)
- A unit measuring illuminance equivalent to lux, representing luminous flux per unit area in photometric contexts.
- Illuminance
- The amount of visible light falling on a surface, weighted by human eye response.
