Hi everybody from Italy.
I am a really ignorant in electronics.
I would know, how can I distinguish an analog xenon ballast from a digital one?

Thanks in advance for your replies.

Ballasti digitali sono molto piu piccoli, ma anche sono piu sensitivo ai danni electrici.
Lemme see if I can get this right :
Digital ballasts are smaller, but also more sensitive to electric currents...
(mind you, I don't speak Italian and can't be arsed to Google Translate ;))

Just because it is Digital does not mean it is better. Digital of itself is NOT better. It is the complete product that makes it better or not.

Some digital ballasts are better than most Analog ballasts. Many Analog ballasts are better than some digital ballasts.

Digital is NOT a "silver bullet" for ballasts as many sellers claim.

Is it true that digital ones need less than 10A while analag ones need 20A to start up?

Is this digital?

Which elements influence the consumption of amperes?
That is not a direct correlation. Its all in the ballast design, not if it is digital or not.
Me, customer, How can I choose a ballast with a low absorption to ignite?

That is not enough info to answer your question. Cant see the control circuits.

In a Hella OEM Ballast is much more electronics, the cpu is a Motoral 68000.
Such cpu was used in a old mac computers :cool:

I read, it tooks around 10 years for develompent, to make the ballast handy for a car.

When switch your car hid on, the ballast goes each time thru around 20 steps. Such as controlling, is the bulb hot?, reverse polarity on bulb, switching down to lower voltage etc.

Electrical damage, but yes. :D

I barely speak Italian myself. It's a shame how I've let myself slip in the, oh, 12 years since I last needed to use it.

That is a "bare bones" ballast I would not use it as something to emulate, I cant even be confident I see the control circuit section in the photos.

Excuse me, I dont undertstand.
Summarizing: it could be a digital ballast but you are not sure?

Thanks.

Hopefully I word this so google translate works well.


I believe that you don't mean Xenon, because Xenon does not need a ballast.

With HID, it is most often a Magnetic or Electronic ballast.

With a low powered lamp like you would see in a car, a magnetic ballast is uncommon. A magnetic ballast will not perform as well. A magnetic ballast will use more power, it will start up slower, it will restart slower.

I have not seen enough to tell them apart. If I had to guess I would say the one you are showing is electronic because the transformer is smaller than the full power of the lamp and it is using a lot of electronics and a transistor in the final stage (the output).

That IS an electronic ballast, NOT magnetic. He is wondering if it has digital or analog controls.

Xenon short arc do use and need a ballast.

Xenon filled incandescent bulbs do not need a ballast.
