Typical light integrators are used in UV printers or "plate burners" instead. Maybe one of those would work too; but you would have to look up the spectral sensitivity of current models.
    What the Metrolux does!!!!!!!!!!! It adjusts the length of a second to compensate for the fluctuations of the light intensity. Some of us don't like audible beaps! Eric, feel free to chime in!

    Beeps are nice for timing dodging & burning. The Metrolux probably has an optional beep function too. Just wish I had an off switch for the neighbor's backyard music.
