lumen/square foot/steradian
Definition: A unit of luminance, describing luminous flux per unit area (square foot) and solid angle (steradian).
Historyandorigin: Similar to other lumen-based units but using square feet as the area measurement, common in non-metric systems.
CurrentUse: Frequently used in the United States for describing the brightness of projectors, displays, or light sources in various lighting applications.
funfact: This unit is often seen in film and television lighting setups, where high-intensity focused light is required.
