Unit: candela/m2 (cd/m2).
The luminance describes the brightness of a surface that emits light either as a light source or by transmission or reflection. The luminance is defined as the ratio of light intensity to the surface projected perpendicular to the direction of observation. Differently coloured surfaces with the same luminance are equally bright.
