True....but have you priced the lamps for DLP projectors lately? It's not unusual for your
lamp operating costs to exceed a dollar an hour.
DLP will be ready for prime time when the light source problem is solved, which I think will
be soon thanks to the development of super long life LED based lamps. Modern LEDs are
available in all colors including white. and the brightness levels are getting ridiculous.
It's only a matter of time before excellent, color temperature correct, high intensity LED
lamps make their entry into the projection market. And they'll last as long as any other part
of the projector if they don't get power spiked.
Right now, top quality CRT projectors still are the high water mark in image quality, but DLP
has gained a lot of ground in just a few short years. When my CRT based projectors are
finally ready to be retired, DLP will certainly be ready even for my demanding standards.
