Thank you David,
At my clocks with blue floor lighting the blue LEDs are on, but tubes stay
off.
So blue LEDs do not help I think (I remember the electron volts are too low,
am I right?)
I think I have some IR-LEDs laying around and test that this night to see
what happens.

Dieter,
It needs a trigger event to start some ionization. I think that a blue or
UV LED will do the trick. Have not tried this myself.

You all surely know the problem, that if a standard Nixie tube is off for
a longer time, say 1 hour, and switched on at night, it takes some time
(0.1 ... 3 seconds) until the glowing comes up.
Does anyone know a method to speed up the ignition in this condition?
I have found out that:
- higher voltage does not make a change
- higher target current does not make a change
- slew rate of the switch (means a sharp pulse) does not make a change
It looks like nothing helps to make it glow immediately.
All the best
Dieter
