Quote:Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths.
Luminosity and Brightness are both ambiguous terms, and are often used interchangeably. Neither guarantees that one is doing eye-equivalent weighting, or talking about total power, though brightness is usually used as eye-equivalent (or detector equivalent).
