This is an arc type light method if I am not mistaken? so is it just a bright electical current passing jumping a gap between two conductors spaced slightly apart? Something like this????? guess I need a pic or technical explanation 
yes, regulated current comes through the ballast into the bulb..
Uh oh... check out this smart guy! 
The ballast does 2 things, starting and regulating.
Since there is a gap between the 2 electrodes in the tube, there is a lot of resistance. The starting part of the ballast provides a spike of voltage to overcome the gap.
Then the regulating part of the ballast kicks in. It is like a constant current type transformer that, obviously, keeps the current constant to maintain the arc (while the voltage can vary). You need this regulation since the resistance of the lamp goes down quick once you've initiated the arc. So if there isn't any regulation, the bulb will just keep drawing power until it destroys itself (or destroying the power source).

im sorry for not knowing alot about HID's

Some Xenon's are projector and some are free-form as well. I lubbed the Xenon's in my Infiniti, but that was more of an elitist thing
"Bros before Hoes" <-- More men need this mentality.

Hey, you're the car HID whiz... call on me if ya wanna know about lighting up a parking lot! 
Now only if I can get a short arc lamp to work in my car... hmmm...

XENON HID lamps do not have a filament. Instead the light is created by an electrical discharge between two electrodes in an air tight tiny quartz capsule filled with xenon gas, mercury and metal halide salts. This improves durability as road vibrations can cause damage to coil lighting technologies. These light sources also produce a blue-white light that is safer because it is closer to natural daylight.
more info here HID FAQ
Are you making lights or building a dooms day machine?????
