Electronic ballasts
Xenon light sources require high voltage to be triggered. Depending on the Xenon generation, fitting rules may differ slightly, but the principle remains that basic measures must be taken prior to manipulating and servicing the Xenon system. Twenty thousand volts (20kV) are emitted by the ballast and the ignitor during the Xenon lamp startup, so it is essential to secure the system power-off for a lighting maintenance procedure.
