I look at the HW10 as essentially equivalent to the VW60. It has the same chip size and lamp wattage, so I expect the brightness to be similar and will probably vary more with throw distance and iris auto/manual settings. Max brightness probably around 800 lumens calibrated or ~500 in low lamp with the auto iris activated. WSreview had a great write up on the VW60. Following this, native contrast should be ~4000 and on/off ~16,000-19,000 calibrated at D65. So, I don't think Jason's numbers are far off. Hopefully, Cine4home or WSReview will do a review on this shortly to get confirmation.
