From a technical standpoint, it could be argued that fluorescent technology is easily as arcane, with its mercury vapor pressure, emissive coatings, discharge regions, non-elastic collisions of electrons, cathode and anode fall voltages.
So, as frontal diameter of the anode reduces, the anode fall of voltage increases, which, in its turn, causes occurrence of the conditions for constricted discharge.
