LCoS is like any other LCDs in that it uses polarized light. This does not 

necessarily mean that half of the lamp light is wasted, because they can 
use a recycling polarizer. Though that will probably increase the etendue, 

so it would work well only with a larger LCoS panel and projection lens...

Do you mind the fact that it is glossy ? LCDs are getting it too...  :-( 
Both my old CRT rear projectors have a dark matte screen, thank god.
