The bulb is placed in the arc gap position of a bipolar TC primary system. This means the enter and exit connections to the bulb are each routed through the 5 winds of the adjacent primaries. At the lowest voltage level of a 8 volt open circuit level obtained by a 3 phase car alternator the discharge acts as an open/close switch similar to arcing in a TC primary. An adjacent neon bulb does not display this quality. With higher voltage inputs this radiative aspect of the discharge disappears.
Three levels of 3 phase voltage applied to ignite a 4 inch krypton bulb. 11.3 volts open circuit is first applied where it is noted that after a time period the "radiative" effects of the discharge acting similar to a tesla primary arc gap then diminish. Then the circuit is operated at the lowest of the three levels; 8 volts open circuit. Finally again the complete disappearance of radiative effects is shown with a 21.8 volt open circuit operation. The bulb is connected between the TC primaries of the bipolar set up, the same place in the circuit where the arc gap would be. 3 krypton discharges 3 krypton discharges View on youtu.be Preview by Yahoo Pioneering the Applications of Interphasal Resonances http://tech.groups.yahoo.com/group/teslafy/
