The ballast steps up the voltage from 12V to a very high amount, but the bulb itself draws less current and runs cooler than halogen bulbs. That's one of the great things about HID, the current goes more into making light and less into making heat, so it's much more efficient.
if you get a well made one it should be the same beam pattern as halogen because they place the capsule in the same place as the filament...

The arc in an HID capsule used to generate the light does not create nearly as much heat as a halogen bulb, because halogen bulbs are incandescent and operate by the principle of running current through a wire will heat it up enough so that it glows, which makes the light (and LOTS of heat). Your headlights should run cooler with an HID capsule inside them.
I think you are confusing voltage with current draw and wattage .....the HID systems I've seen use the ballast (step up transformer) to multiply the voltage and to create the spike in voltage to establish the arch. I am not sure what voltage level it operates at, but I would think it would be similar to a florescent lighting ballast.
voltage x current = watts
voltage x current = watts
which one is good for a integrai think the 6000k sounds good. i like the with the purple beam like the BMWs. whats better phillips or hella

arnt the ballast like 30k volts or so? there actualy cook to the touch unlike normal bulbs. no long term damage, and the only effect would be wanting hid's on all your cars.

I have read on several HID retrofit websites that you should install a harness that has a relay in it to power the ballasts. Sure, they don't draw a bunch of power while on, but for the first few seconds of power up, they draw considerable more power than standard headlamps and will deteriorate the stock wiring.
