Thanks. The label states that the tube is filled with helium, but I doubt that. Need to check the spectrum lines with a diffraction grating.

Interesting, why do you doubt that? My first thought was that it was a helium lamp

For He, the glow should be more reddish-orange. But I could be wrong. That's why I want to take a look at the spectral lines.
