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.

Candela per Square Foot

cd/ft²

Definition

The Candela per Square Foot is an imperial unit of luminance, representing the luminous intensity per unit area using the square foot as the area unit. It is commonly used in countries that employ imperial measurement systems for lighting applications.

History/Origin

Developed as part of the imperial system of measurements, this unit provides a practical way to measure surface brightness in contexts where square feet are the standard area unit. It bridges the gap between metric and imperial systems in lighting applications.

Current Use

Used in lighting design and engineering in countries using imperial units, particularly in the United States. Common in architectural lighting, display specifications, and lighting calculations where square footage is the standard area measurement.
