Nixies exhibit negative resistance and will maintain their glow at typically 20 V to 30 V below the strike voltage.
2.
The lamp provides no indication below the strike voltage of the neon lamp, and so cannot detect certain hazardous leakage conditions.
3.
:To'dim'discharge lamps you need to reduce the current through them without going below the striking voltage of the tube.
4.
The increase of strike voltage for shorter electrode distances is related to too long mean free path of the electrons in comparison with the electrode distance.
5.
The mixture is easier to ionize than either neon or argon alone, and lowers the striking voltage at which the tube becomes conductive and starts producing light.
6.
The striking voltage depends on the spacing, the gas pressure, and the type of gas ( ref http : / / en . wikipedia . org / wiki / Breakdown _ voltage ).
7.
As the design requires that twice the supply voltage must be lower than the cold-cathode striking voltage ( or the tubes would erroneously instant-start ), this design cannot be used with AC power unless the tubes are at least length.
8.
:: Disconnected from the tube, the ballast will produce a back-emf of several thousand volts ( depending on leakage ), but the strike voltage is typically 600 to 1000v, or lower for shorter tubes, so this high voltage should not normally be generated ."
