I am in the process of upgrading my 35W HID, and I have researched 100W HID kits. In working out a suitable battery, I looked at the current rating for the ballasts. Most 100W ballasts on aliexpress state that the current consumption is 5A. This puzzles me, as I understand that Volts x Amps = Watts.
So, 12v x 5A = 60W. The efficiency is less than 100%, so the HID bulb should get even less than 60W. Apart from the obvious (incorrect specs), what am I missing here??
