I member back on the PHillips board (which is down), that someone found out how many watts or amps would be going between the two terminals on the Hella D2 ballast if it was ignited without a bulb attached. Does anyone member that figure?

You can't measure it at the ballast beccause the voltage is too high. During startup, it may be around 25,000 volts and 15-30 amps. As for Watts....watts is a unit of power which is how much work you can do over a period of time...igniting without bulb attached would be hard to measure how much work you are really doing (maybe heating up the air and some noise from that expansion of air).

If ballast draws around 13 amps at startup, maybe 3 amps will disappear into internal heat losses, so we have 12volts x 10 amps which is around 120Watts. That should give us 120/23000 volts, which is 0.005 amps.
