Re: [EE] NE2 ignition voltage in an electric field

For a DC or low-frequency (<1MHz) field, it should be close to Vignition/d
where d is the electrode spacing inside the lamp, I think. I don't think an
external DC field can keep the lamp lit because there is no mechanism to
provide power input (no current flow).
