The substantial voltage that is utilised to produce the spark is all around twenty,000 volts, which is significantly higher than a car’s standard 12 volt offer and so a metal box, named a ballast unit, is fitted to help improve the voltage. When the spark has been created and the bulb is illuminated the voltage drops down to a constant 85 volts.
The xenon fuel belongs to the group of aspects recognized as the noble gases, and is held inside of a single sealed glass tube earlier mentioned the base of the bulb.
