Fom Wikopedia CANDELA Definition

The frequency chosen is in the visible spectrum near green, corresponding to a wavelength of aboutnbsp;anometers. The human eye is most sensitive to this frequency, when adapted for bright conditions. At other frequencies, more radiant intensity is required to achieve the same luminous intensity, according to the frequency response of the human eye. The luminous intensity for light of a particular wavelength lambda; is given by where I_v(lambda;) is the luminous intensity in andelas, I(lambda;) is the radiant intensity in W/sr and is the standard luminosity function. If more than one wavelength is present (as is usually the case), one must sum or integrate over the spectrum of wavelengths present to get the total luminous intensity.
