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.
