There does seem to be a consensus of sorts in the industry that the Barco is not as light efficient as the Christie and NEC. I don't know this to be fact as I have not been in a position to do actual A/B tests. It's rather early in the game to have D-Cinema projectors laying around like Simplex and Century projector heads and lamphouses.
Some say the light difference if any, is due to Barco's smaller integrator rod (size matters?) perhaps it is the reflector design or simple difference in age of the optics or the coatings.
What I don't understand is why one 1.2 chip projector looks different or better than another apart from absolute light output and/or absolute color temperature.
In Mark's recent changeout, he used the very same lens from the old projector in the incoming ZX so we can eliminate that I guess. I don't know Mark ran the same material in both projectors back to back, or if this is merely an impression Mark was left with, and of course impressions are always open to question unless there is data to back it up, i. e., test patterns, contrast ratio, etc.
I have done two installations with Barco DP2000's and the results look excellent on their own merits and am about to do a 10 Plex with 10 ZX; 7 with the new full chip triple flash 3D capable projectors and 3 of the older version ZX's. Ought to be interesting. [ 12-30-2008, 02:22 AM: Message edited by: Sam D. Chavez ]
