LCD back light longevity ?

[gothic_hobbit]

How long does an average LCD back light last for ?

I have seen 10000 hours being quoted here and there, but would like clarification to whether or not this is the case.

For your information, I am referring to cold cathode fluorescent lighting

or if he owned one from a while ago and wondered how long it had left.

This.

I have an LCD display clocking on for 10,000 hours.

How much time would you reckon it has left ?
