The MM-4e light booth provides five spectrally different sources of illumination for precise color comparison and visual color assessment, easy detection of metamerism, and environment lighting duplication. Included with the MM-4e is a new digital control that confirms which source you have selected with an illuminated push button. This also provides easy one touch automatic light source sequencing.
