The light source is LED.. It will never go out unless the something went terribly wrong with the cooling.. The life time only means it emit 70% of its initial output after 50,000 hours.. An LED will always emit light no matter how long it is running for, the only thing that changes is the brightness...
No, your math is right maty. It isn't 'forever' but it will take a damn while. Let's not be ridiculous though, and let's assume a more normal workshift for that projector. 8 hours per day. That's 17 years. Not sure you'll want to use that old and disturbingly low resolution thing in 17 years...
I'm hoping that we hit the point where we can project things on the order of the wavelength of the specific frequency of light in question, (making resolution irrelevant, because you can't get any better) in a few decades...
To the person who mentioned something about 70% brightness, and LEDs will always emit light, you're forgetting one scenario. :P
What if, say, someone uses an LED without a current-resisting resistor, thus causing the bulb to actually burn out? I've done it once or twice just for experimentation, and I'm pretty sure that the couple LEDs I killed no longer can emit light. Just being picky. ^_^
The cool thing about leaving out the resistor, then turning up the voltage, is that the LED changes color before it burns out.
I would be *VERY* surprised if this was run with a simple resistor ballast.
They probably have a much more sophisticated current mirroring setup going on. One LED per channel, always: Or you risk thermal runaway on a single LED causing it to draw more current and blow up.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
And what if the bulb goes out?

And what if you actually read?
There is no bulb. (Read LED)
A better question would be, "what if a light-emitting diode went out?".

As assumption here, but with such a bold claim they'd have to back it up and probably have the bulb under warranty... probably. :P
"Forever" = "24 hours a day for 5.71 years". ;) Unless my maths is wrong, do correct me if I am.
Nice projector, this is one of those liquid cooled ones right? Awesome, awesome, hey, is that a dead pixel?
No, your math is right maty. It isn't 'forever' but it will take a damn while.

Ha. Projectors with "Resolutions" in 17 years.
