Christie LHD878-DS Laser Projector Review – Performance

Christie LHD878-DS Projector Review – Performance: Brightness, Audible Noise


While Christie advertises the LHD878 brightness as 8775 ISO lumens, the industry standard for measuring brightness is ANSI lumens. The LHD878 brightness is rated at 7800 ANSI Lumens. Regardless, the fact that a mid-size laser projector can deliver nearly 8,000 ANSI lumens is amazing especially when you consider that only a decade ago, 2,000 lumen projectors were the favorite rental and staging projector options for auditoriums and hotel ballrooms.

Just how close did the LHD878 come to hitting its target of 7,800 ANSI lumens?  I measured its brightest mode, Dynamic, at full wide angle – this is with the iris wide open, so the most amount of light gets through. I took 3-4 readings about 15-20% out from the center of the lens which should give a pretty good approximation of ANSI lumens.

Christie LHD878 Brightness (Dynamic mode, Normal Light Output): 7710 Lumens

At wide zoom, Dynamic mode.

The LHD878 measured 7710 lumens which is very close to Christie’s brightness claim. For the rest of the modes, I measured them at mid-zoom, so the iris is closed halfway. This is because it is more common for a projector to be zoomed in a bit rather than installed at full wide angle.

Audible Noise

The LHD878-DS was a little louder than a typical home theater projector which is too be expect considering it is an 8,000 lumen business projector. Even in my small room, no one had to shout, or even significantly raise their voice to talk over it.

Christie quotes the LHD878’s noise level at 41db at full power and 32db in ECO mode. Relative to the amount of brightness the LHD878 can output, it is quiet projector. In most classroom and conference room applications, the projector is quite enough not to be distracting.
