Certain 'rapid start' lamp assemblies have a fairly low impedance, because they are trying to ("rapidly")warm a filament. Energy doesn't accumulate from one cycle to the next.
However, electronic ballasts rely on a different method to raise voltage to reach ionization. There's no filament circuit to drain energy when the lamp isn't ionized. In this case, energy accumulation from one cycle to the next may be possible. That's why I use an incandescant lamp (my cheap bleed resistor) in parallel. In a theatre it's easy to hide one backstage and then my (blacklight, usually) lamps come on and off when I want them. |
