In fairness, pretty much any current sub-$1k projector should best the 8-year-old 6500UB. Calibrated, that unit only hit around 700 lumens in its best picture modes...

Where the original US model could do with a stacked lightengine, the Euro version is measured as low as 550 lumens with correct colours. Ekki at Cine4Home had first reviewed the selected pre-production unit of the US version that was good colour out of the box and still provided 1100 lumens (700 matching the Rec. 709 standard), so interesting, the EU retail version tested by Gregory (Kraine here) only does half that, so hang on to your CRTs;-(.
It's certainly somewhat mystifying. The original pre-production LG PF1500 US model hit 1100 lumens without calibration (that's a very respectable number by most accounts; especially for smaller screens - or larger ones in very dark rooms). Better yet, it calibrated to comfortably over 700 lumens.
But then the post-release US model dropped quite significantly to 950 lumens maximum.
And then the EU model is a further 150 lumens less than that already-lower figure:

We also measured two EU-models
- Both are around 800 lumens max and 610 lumens calibrated.
I was hoping the sub-1400 lumen brightness of the pre-production model would be lower
than the finished product: but the opposite is the case instead; and the finished product is now actually further away from its brightness claim, not closer.
LG is breaking new ground here (this is still the brightest LED in this price bracket): but what could the reason for the numerous reductions be? Might they be worried about the longevity of the light source driven at full power? (This is their first Osram-powered LED projector). Did they find it was getting hotter than intended with the relatively simple cooling system in place? Or is it just firmware bugs that have crept in?
At least one enthusiast has taken this up directly with LG:
LG have responded that they consider such large brightness discrepancies abnormal since manufacture of the regional models takes place at the same factory - and are looking into it.
Guess we'll find out soon enough!
