Harkness Screens™ recommends Perlux® screens for digital cinema auditoriums because they can reduce digital operating costs by enabling reduced power consumption, smaller lamps, and less frequent lamp replacements. Perlux® screens are also ideal for use with laser projection enabling laser projectors to be operated at lower power levels, elongating maximum light output from the projector for the longest possible period of time. The unique coating technology of Perlux® HiWhite incorporates Harkness' Nanolast™ technology creating a truly white surface with ultra-wide viewing angles, outstanding rendition of colours and contrast and extremely robust.
