I always thought all in the title were the same, but from what i have been reading im now thinking they arn't.

If a car come with xenons from the factory are they hids but not projectors?

Which is best?

Thanks for the help

 

You don't see many PROPER HID setups that aren't projector.

Xenon: refers to one set of lamps, or should.
Has also been b@stardised to mean HALOGEN bulbs with a bit of Xenon in, or even blue coloured halogen bulbs

Bi-Xenon: originally used to mean cars fitted with TWO sets of Xenon lights, one for dips, one for maion beam. Then became used for those cars using ONE prjectyor fitted with a movable mask, which then does dip/main.

Also used for the odious H4 Xenon retrofit bulbs.

Projectors: identifiable by the bullseye lens, it is this lens and NOT THE BULB that gives the bluish tinge to standard Xenon lights.
Originally did main, or dip, now can do both, although PROPER Bi-Xenon using TWO projectors is obviously better

 

So if I understand correctly,

If I see a high spec car merc, jag etc with the bullseye lens that moves, its the best set up poss?

Thanks again for helping me clear this up

 

Not quite, it's not the bullseye lens that moves but a small screen that drops in front of part of the light output from the bulb, giving the cutoff we know, it ends up looking like this:

\_____ \_____

The bits at left are the "fingers" of light that help to light up the nearside edges of the road, road signs, pedestrians, etc, without shining in the eyes of oncoming drivers.

In countries where they drive on the RIGHT, THEIR beam cutoff would look like this:

____/ ____/

When main beam is selected, the little covers either drop away, flip up, or something like, allowing a full spread of focussed light.

Now, in a TRUE Bi-Xenon setup, you would have ONE set of lights doing dip beam, with a cutoff showing as above. Then, when main beam is selected, a SECOND set of lights comes on doing the full main beam, while the first set stays on.
Thus you have TWO sets of lights and double the light output.

Given that a 35W Xenon bulb is approximately 8 times brighter than the standard 60W halogen equivalent, you have some light output there.

To get some idea, have a look here:

Post 26. The last pic shows a halogen Morette setup, (which isn't bad on it's own), with ONE PAIR of HID Xenon driving lights.
