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.

Nox

nox

Definition

The Nox is a unit of illuminance equal to one-thousandth of a lux, representing very low levels of illumination. It is used for measuring extremely dim light conditions, such as those found in night vision applications, astronomical observations, or specialized scientific measurements.

History/Origin

Developed for measuring very low illumination levels that are below the practical range of the lux. The nox provides a convenient unit for expressing extremely dim light conditions in scientific and technical applications where precision is important.

Current Use

Used in specialized applications requiring measurement of very low light levels, such as night vision technology, astronomical photometry, and scientific research involving extremely dim light sources. It provides a practical scale for quantifying near-threshold illumination conditions.
