Lumen per Square Meter

lm/m²

Definition

The Lumen per Square Meter is a unit of illuminance that is numerically equivalent to the lux. It represents the luminous flux per unit area, emphasizing the flux aspect of light measurement and providing a direct relationship between light output and surface illumination.

History/Origin

Derived from the fundamental definition of the lux as one lumen per square meter. It provides an alternative way to express illuminance that emphasizes the luminous flux component, making it useful in calculations involving light sources and their output.

Current Use

Widely used in lighting calculations and photometric applications where the relationship between luminous flux and surface area is important. It provides a practical way to understand illuminance in terms of light source output and surface coverage.
