does it require more voltage to start them up? how about when they are in use? thanks...

 

I think they use more voltage to start up, but once started I think they use less.
Dont' quote me on that, please correct me if I am wrong.

they take more power at startup but consume less afterwards. More amps, not sure about voltage..

 

The initial draw is pretty substantial but they do require less voltage than stock halogens.

 

Initially, when the system is started, the ballast produces pulse voltages ranging between 18-20kilovolts and these pulses continually cycle until the arc is established.

 

Amperage, not voltage.

voltage shouldnt vary. I dont think that wouldnt work well in a 12vdc circuit

considering v=ir, current should remain the same. the initial "boost" you see at the initial warm up is from the ballasts charging. (capacitor discharging).


then again, i'm the guy at the expo who was wondering why the cigarette lighter wasnt working....looking at wrong fuse

 

Voltage does vary. 12-14.6 volts

Considering E=IR (Not V=IR), E=voltage I=amps/current R=resistance

Voltage should be 14.4 volts with the motor running.
Resistance of the ballast does not change.
Current(amperage) draw will be higher (at startup)

Current does not remain the same, hence the reason most hid kits tell you to put in a higher amp fuse.
