I'm working on a Nixie tube clock and have read that nixie tubes have a life of about a year.
Does anyone know of ways to extend the lifetime of a tube?
Can you use a mosfet to switch the high voltage power supply using PWM or would that just end up delivering a lower average voltage?
Specifically I'm using IN-14 Tubes, and plan on driving them with 170VDC, 3mA.
Any input is appreciated! Thanks!

Not all are created equally. Also note your spec final page end.. to operate all elements if not in use for extended periods...
Suggest a sleep mode to disable display if inactive on 0000000
Also reduce cathode current to 1.5mA and Cathode voltage to 170
