Lumen per Square Centimeter
lm/cm²
Definition
The Lumen per Square Centimeter is a unit of illuminance equal to 10,000 lux, representing the luminous flux per unit area using the centimeter as the area unit. It is used for measuring very high levels of illumination, particularly in concentrated light sources or small area applications.
History/Origin
Developed as part of the CGS system where smaller area units were commonly used. It provides a convenient way to express high illumination values without using very large numbers, particularly useful in scientific and technical applications.
Current Use
Used in specialized applications requiring measurement of very high illumination levels, such as laser technology, concentrated light sources, or scientific research involving intense light fields. It provides a practical scale for quantifying high-intensity illumination.

Phot
ph
Definition
The Phot is a CGS unit of illuminance equal to 10,000 lux, representing one lumen per square centimeter. It is a larger unit used for measuring very high levels of illumination, particularly in scientific and technical applications where high light intensities are common.
History/Origin
Developed as part of the CGS system of units, where the phot provided a convenient way to express high illumination values. It was widely used in scientific literature and technical applications before the adoption of SI units became standard practice.
Current Use
Primarily found in older scientific literature and specialized technical applications. It provides a practical scale for measuring very bright light sources and is still occasionally referenced in photometric research and historical technical documents.
