Few questions about lcd projectors and bulbs used in these:
How does metal halide bulb used in LCD-projector acts when it's life
time is over? Does it burn out instantaneously like normal glow bulb or
does it dim out step-by-step?
How does projector know when to bulb is burnt out? Is it possible to
measure or test metal halide bulb someway?
I know that ignition voltages can be very high (kV). Is there way to
measure if projector is trying to ignite bulb at all?
