LED light in film scanners and longevity

    We know that the Nikon film scanners use LED for their light source,
    and that the life span of these lamps is very long.

    But it is said that the Konica Minolta 5400 II also uses LED, and that
    the light source in that scanner therefore has a similarly long
    lifetime. Is this correct, or are we talking about different light
    sources?

    In the Nikon scanners, there are four LED's, one infrared and thre for
    R, G, B if I have understood correctly.

    I am not sure if the Konica Minolta has this setup, but if not that
    scanner needs a color filter in order to make color, and this filter
    will fade. Thus, the light source in the Nikon scanners will last
    longer than that one found in the Minolta unless it has the same
    construction with an array of color LED's.

    Does the Minolta have that, or does it not?
