Interesting that the supply mentions 3.2kV; the nominal anode voltage is 1850 volts. As with nixie tubes, I suspect the current is the critical parameter as it determines the brightness (amount of phosphor burn). And, like nixies, there is a minimum voltage required for illumination. So, there isn't an exact operating voltage that must be strictly adhered-to. Also, I have not found any info that suggests harmful radiation (X-rays) are produced anywhere near 3kV, so I wouldn't worry about getting nuked from a NIMO tube or small monochrome CRT.
I've run my NIMOs just below the 30uA current and in the vicinity of 1850V for less than 50 hours of operational time, and with a UV light source I can see slight phosphor burn. I dont run it as a clock very often, fearing that I will either burn the phosphor or burnout the filaments, yet at the same time I do want some enjoyment out of this multi-year project. Decisions, decisions......
