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.
