English Wikipedia has an article on:luminous intensityWikipedia
luminous intensity (plural luminous intensities)
(physics) A measure of the power emitted by a source of light; equal to the flux density per solid angle
At other frequencies, more radiant intensity is required to achieve the same luminous intensity, according to the frequency response of the human eye. Source: Internet
The luminous intensity of light-emitting diodes is measured in millicandelas (mcd), or thousandths of a candela. Source: Internet
The modern unit is defined in a more precise and repeatable way, but was chosen such that a candle's luminous intensity is still about one candela. Source: Internet
Another three base units (for temperature, substance and luminous intensity) were added later. Source: Internet
Examples A common candle emits light with roughly 1 cd luminous intensity. Source: Internet
Origin Prior to 1948, various standards for luminous intensity were in use in a number of countries. Source: Internet
