Lumen per Square Centimeter Steradian

lm/(cm²·sr)

Definition

The Lumen per Square Centimeter Steradian is a unit of luminance using square centimeters as the area unit. It is equivalent to 10,000 candela per square meter and is used for measuring high-luminance sources with more manageable numbers.

History/Origin

This unit was developed as a practical alternative to the square meter unit when dealing with high-luminance applications. It provides more convenient numbers for measuring bright light sources and is commonly used in display technology and laser applications.

Current Use

Frequently used in display technology, laser systems, and high-intensity lighting applications. Common in measuring LED displays, plasma screens, and other bright light sources where precise luminance control is essential for performance and safety.

Foot-Lambert

fL

Definition

The Foot-Lambert is an imperial unit of luminance equal to 3.4262590996 candela per square meter. It is commonly used in display technology and lighting applications in countries that employ imperial measurement systems.

History/Origin

This unit was developed as an imperial equivalent to the lambert, using square feet as the area unit. It provides a practical way to measure luminance in contexts where imperial units are standard, particularly in display technology and lighting applications.

Current Use

Widely used in display technology, particularly in the United States, for specifying monitor brightness, television luminance, and other display characteristics. Common in consumer electronics specifications and lighting applications where imperial units are standard.
