Interesting that H79 is always been quoted much brighter than H77 or H78 DC2 but judging by those numbers, your H78 DC2 has same lumen output as H79.
No the H77 had 100 less but the H78DC2 always had 100 extra too, giving much speculation on how that worked it was probably because of the extra mirror speed that resulted it better control (longer) times on the colorwheel or changes to the powerunit.
The messages H77 got in europe when they announced the upgrade :
17-03-2005 ThemeScene H77 / H78
Brightness: 1000 Lumens
The new ThemeScene H78 delivers substantial image quality enhancement over its predecessor, the award-winning H77. Newly developed technology by both ThemeScene and Texas Instruments enables the H78 to offer stunning picture quality:
1. Colour accuracy has been enhanced on a wider range of signal types
2. PAL and 50Hz High Definition (European High Definition) image quality has been further optimised
3. Grey scale linearity has been improved, especially in the important low light, dark areas of images.
4. Faster Pixel response times have yielded improvement in both Brightness and Contrast Ratios - Brightness has increased from 900 to 1000 Lumens, Contrast has risen from 3500 - 3800:1
These improvements combine to produce an image of unrivalled colour balance, accuracy and motion fluidity resulting in exceptionally natural and cohesive images.
Existing H77 owners can benefit from these improvements by having their units upgraded to H78 specifications. For a nominal fee of 150, upgrade to H78 specifications, re-calibration and return shipping.
