Title: HID v Halogen
Post by: mrjimbo on 17 August 2010, 16:02:11
Which would draw most current a HID bulb or a normal Halogen bulb ?

Just curious, something i've often wondered  ;D

IIRC HID's are 35W and your halogen tunsten type are 55W
V=IR if you want the current.  :y ;)

Higher for initial power up then less when "up and running"

HIDs have a power supply which fire up (which is why they "flash" when powered up) at a couple of thousand volts and then back-off to run at a hundred volts or so. The power supply is the metal box screwed to the headlight and have an "HT" cable to the bulb.

The technology is the same principle ss a flourescent light - and also the backlight on a LCD tv.

The inrush current when HIDs fire up is very high - at about 20amps, this reduces down to about 3amps when they stabilise which takes a few minutes.

Yes, with lots of insulation around them.
