FAQ

A Nixie clock displays digits using sealed glass tubes with cathodes shaped like numbers. A low-power glow discharge lights one digit at a time, creating a crisp, retro look.

ZIN-70 is our largest tube family with bolder, taller numerals; ZIN-18 is more compact for smaller desks. Both support the same core electronics and features.

They are safe for normal use and not radioactive. Tubes are sealed and contain small amounts of inert gases (e.g., neon/argon).

Our ZIN-series tubes (ZIN-70, ZIN-18) are newly manufactured. Some legacy models use selected vintage tubes (e.g., IN-14) where specified.
