The ballast will require filament continuity at both ends of the lamp to sustain self-oscillation because they form part of the circuit. When one end burns out, the oscillator stalls. If you were to short out the open-circuit filament, the oscillator will work until something else fails. In a throw-away CFL, often a transistor fails short-circuit and blows the in-line fuse.You meaning: When only one wire connected to each end of the lamp, it will run most EOL lamps to vacuum loss?
