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.

Foot-Candle

ft*c, fc

Definition

The Foot-Candle is an imperial unit of illuminance, representing the illuminance produced by a standard candle at a distance of one foot. It is equivalent to approximately 10.76 lux and is commonly used in countries that employ the imperial system for lighting measurements.

History/Origin

Developed in the United States and other countries using imperial units as a practical measure of illumination. It was based on the light output of a standard candle at a distance of one foot, providing an intuitive reference for lighting levels in everyday applications.

Current Use

Still widely used in the United States for architectural lighting, workplace safety standards, and general lighting applications. It provides a familiar unit for lighting professionals and is commonly referenced in building codes and lighting specifications.
