Thanks Kraine. From that link it looks like the lamp is the same $1000 one that Sony used in the VW100:

It is fairly obvious that the new projector uses a Xenon lamp. There are certain advantages to using a Xenon lamp if one watches films and commensurate with a top of the line machine from a company, they elected to use a Xenon lamp.

This subject has been beaten to death previously. And there is much more to how your eyes see a picture than just how a meter measons the color points For example, three DLP chip machines have a more satisfying solid image than one chip DLP machines. Much less filtering has to be used with a Xenon bulb than with a UHP bulb. Light output considerations aside, because filtering must necessarily reduce light output when the limit is reached for one color, I suspect that there are other picture quality considerations which come into play. I leave it to others todiscuss them where they have been discussed in various threads.

How does it really work? How do we see and interpret color, motion, and contrast? I still have a significant amount of my investment in bleeding edge vision companies and some personal challenges in this area so I try to keep up as much as possible.

Lawguy. I am issuing a preemptory challenge. I was making analogies, even I know that most three chippers do not use Xenon lamps.
My analogy was illustrative that while a three chipper and one chipper will measure the same xyYs, the appearance on the screen of the colors to your eyes will differ. I was trying to illustrate that there indeed can be differences to ones eyes between a machine lit with Xenon vs UHP. And your filter argument is just meant to obfiscate the issue. The degree of filtering a projector must employ does indead have an effect on image quality. Further, a Xenon lamp will drift with age much less than an UHP one.

I'm not sure why any of this would be a mystery. How colors are defined by measurements is accepted scientific fact...
