How long does a xenon flash tube last? Like what is the average life expectancy? Can the flash be replaced?
I am just wondering because I want to start using a cam driver with forced flash on my k850i and I don't want to mess up my flash.
Thanx :)

On my K810 it served quite well for 2 years. Wouldn't expect anything less than 4.

Ok cool but how much did you use the flash? An did it stop working after 2 years or did you get anther phone?

Out of 1650 pics, at least one third of them were taken with the flash.
and no, I just got a C905. My dad's using the K810 now.

Besides, nothing is practically being "wasted" in the flash tube. There's no wire that burns up after too much use (a la incadescent bulbs) and no other gases, with which the xenon can react (even though it is an inert gas).
What happens is that a very strong current (prepared in the capacitor) is let through the xenon gas, making it glow really strongly. The gas just decays after time from all the photon emissions and even downright escapes from the tube.

Ok and the proses of the gas decaying probably takes a while ,right?
