The lux (symbol: lx) is the SI unit of illuminance and
luminous emittance. It is used in photometry as a measure of
the intensity, as perceived by the human eye, of light that
hits or passes through a surface. It is analogous to the
radiometric unit watts per square metre, but with the power
at each wavelength weighted according to the luminosity
function, a standardized model of human visual brightness
perception. In English, "lux" is used in both singular and
plural.
