Luminous Intensity (I, cd) is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle.
Luminance (L, nit) is a photometric measure of the luminous intensity per unit area of light travelling in a given direction.
Illuminance (E, lx) is the total luminous flux incident on a surface, per unit area.
