Yes. Much like many consumer projectors.

Most of them are actually DLP these days, with LCD-based ones occupying the majority of the ultra-low-end (XGA and below).

This is true. But it was only a decade ago that most projectors were just LCDs with a ridiculously inefficient lamp.

Even the ultra-low end are frequently DLP these days, just replacing the powerful bulb with an under powered LED.

I've also seen that Sony and Epson are selling laser illuminated projectors as opposed to the more common LED/halogen/etc illuminated projectors. Apparently for high luminosity, laser becomes more efficient and less prone to damage than both LED, halogen, incandescent, argon/xenon etc.

But it disappoints me that these projectors just use the laser for illumination. I'm waiting for when we have laser-on-DLP without filters type projectors.
