Appreciated.

I don't speak Russian unfortunately.
But .. I can tell you from the data sheet by guessing, inference and experimenting.
B in Russian = V in English.....
Line 1 is the kandela out. 40/M2
Line 2 is the viewing angle 50 degrees
Line 3 is the maximum voltage that can be applied. 250
Line 4 is the ionizing voltage. 140V
Line 5 is the maintenance voltage. 70V
Line 6 is the maximum milliamps at which the bar is fully lit. 12mA
Line 7 is the bar length lit minimum and maximum. 20-97mm
Line 8 Linearity +/- 4%
Line 9 is possibly the lifetime of the tube ? Although the 2 data sheets seem to disagree.
