Not sure how long your cold cathode tube will last, but...

Cold cathode tubes seem to vary between 6000 hours in a scanner application, up to 30,000 hours in a flourescent lighting application.

10,000 hours came up fairly often, which is a year and a bit.

As the lamp gets older, it will get dimmer, until the converter unit will not be able to maintain a current flow across the tube. Then it'll just fail to ignite, or suffer from cathode spluttering.

is spluttering an actual term used for cathode tubes?
