'Leuchtkraft' (luminosity) is made up of 'Leucht-' (shining/light) and 'Kraft' (power). The word therefore refers to the power or intensity of shining and can also describe the intensity of colors.

In its technical and physical meaning, 'Leuchtkraft' (luminosity) often appears with words such as 'hoch' (high), 'gering' (low), or 'messbar' (measurable).
