lumen/sq. meter/steradian
Definition: A unit of luminance, expressing the amount of luminous flux per unit area and solid angle.
Historyandorigin: This combines the lumen (a unit of luminous flux) with square meters and steradians, the units for area and solid angle, respectively.
CurrentUse: Common in photometry, particularly when measuring light emitted from a source in a specific direction or angle.
funfact: This unit is useful for describing light distribution in projectors and lighting fixtures.
foot-lambert [fL]
Definition: A unit of luminance in the imperial system, equal to one candela per square foot.
Historyandorigin: The foot-lambert is derived from the lambert but uses square feet as the area measurement instead of square centimeters.
CurrentUse: Commonly used in the United States, especially for older cinema and television technologies.
funfact: The foot-lambert is still used to describe screen brightness in certain vintage or legacy equipment.
