13. Illuminance
    In photometry, `illuminance` is the total luminous flux incident on a surface, per unit area. It is a measure of the intensity of the incident light, wavelength-weighted by the luminosity function to correlate with human brightness perception. Similarly, `luminous emittance` is the luminous flux per...
