Frequently Asked Questions
The questions we get most often. For deeper reads — comparisons, buying criteria, the history of the tube — see the Blog.
Yes, when designed properly — but they typically use ~170V DC internally to drive the gas discharge. Buy from reputable makers, don’t open the case unless you know what you’re doing, and you’ll be fine. IPS “digital Nixie” clocks sidestep the question entirely by running off USB-level voltage.
Real Nixie uses vintage or small-batch gas-discharge tubes — the glow is physically produced by ionized gas. IPS “digital Nixie” uses miniature IPS screens housed in a tube-shaped envelope to simulate the look. IPS is safer, more customizable, longer-lived, and usually significantly less expensive.
Yes. Original tubes are typically rated for 10,000 to 200,000 hours depending on the model (ZM1040, IN-18, IN-14, etc.) and how hard they’re driven. Modern IPS reproductions share the lifetime of a good backlit display — usually 30,000+ hours — and have no high-voltage wear mechanisms.
