The Bencher VP400 copystand polarizers have no problem with
the four 500W bulbs.  It does get hot.  And you can see your
electric service meter spin faster (frown).  The Bencher 
polarizer panels are about 6 inches away from the light 
sources, so the heat isn't a problem for them, nor for the 
vinyl disc on the platform.  I find that there's no need 
to use cross polarizers except on the glossiest materials.
