Just how close did the LWU530 come to hitting its target of 5,000 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. That should give a pretty good approximation of ANSI lumens unless a projector brightness rolls off excessively at the edges which this projector does not do.
Christie LWU530-APS Brightness (Dynamic mode, Normal Light Output): 4862 Lumens
At wide zoom, Dynamic mode.
The LWU530 measured 4862 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.
