Key Terminology
-
Foot-lambert [fL]
-
An imperial luminance unit representing luminous intensity emitted or reflected from a surface per unit projected area; often used in cinema and projection screen brightness.
-
Kilocandela per square meter
-
A metric luminance unit equivalent to 1000 candelas per square meter, used in photometry and display engineering to quantify perceived brightness.
-
Luminance
-
The measure of luminous intensity emitted or reflected from a surface per unit area in a given direction.
