You can't overly increase the lumens on DLP projectors without it lowering the contrast unless you put VERY expensive parts in them (very), and even then you can only do it so much. Reference level DLP's sometimes have even less lumens in their best modes usually than this, or about the same.
The hc8000 is brighter than the hc4000 by a little, the hc4000 was around 1100 lumens in its brightest mode, whereas the hc8000 can actually hit 1300 in 3D mode.
This would put the hc8000's 3D mode brighter than the Benq w7000 3D mode, even though the Benq is much brighter in 2D. For enthusiast setups, we don't care about lumens in the brightest modes as much as we care about it also having a mode with very high contrast.
What we are hoping is a DLP that can do 1300 lumens in 3D (this beats the Optoma hd33, Benq w7000, Optoma hd8300, Sony hw30es, and JVC RSx in 3D mode), and still give us the option of toning down the lumens with the manual aperture which will also boost native on/off. If this PJ is tested well by Zombie, it is exactly a perfect fit for me on my High Power 2.4 gain Da-Lite screen.
