That's true, and has been realized with the Kohl AG, Chemnitz apparatus:

(see item 95'940 in the list below the figures)

At Bern-University is the real coil and "lamp":

I've seen it working, but unfortunately had the camera not with me. 
Interesting point is: the bright zones of the tube are at the current 
maxima, in contrast to the voltage maxima of the corona-zones of the 
wire discharges. The "lamp" seems to be just a vacuum glass tube with 
a residue of probably air only (pressure unknown). The glowing zones 
are very bright, compared to the corona.

Best regards,
