The new A6's xenon lights.

[Ace]

I was wondering something
for a few days now when i am driving around i come across a new A6 avant.
LED tails and bright blue xenon's.

does anybody know which Kelvin level those things are ?
or does Audi give you a option on that ?

Usually most oem hid bulbs run at 4300K. This will give you just a white light with no tint.

Based on that I assume that A6 runs the same kelvin temp.

I myself plan to run a 5800 or 6000K for a slight blue tint in the light. The tint will be reduced by projector, as it does filter some color of the light.

yeah thats what i expected also.
but this was a brand new A6 wagon and it already had a more blueish tint then white.

reason i am curious is because the way it looked was the way i want it to look.
i tried to make a picture but the car was driving to fast both the one i was in and the A6

defintely has a blue tint. i say 6000k.

It's the projectors that create the blue tint, not the actual bulbs.

You might want to double check your information.

To my knowledge. The projector is used to filter out the light. It does not give a tint. It also shapes the beam. Example, if you look at your headlight beam against a wall head-on, you will notice that the left corner is not as high as the right corner. There is a small amount of blocking in that area to try to keep the headlight from oncoming traffic.

On the HIDs they are measured in Kelvin Tempertures to determine the color. This is based on light spectrum graph. a 3000k gives you a yellow. 8000k purple blue.

Now you will see some lights claiming 12,000K. They are somewhat made up. These temps technically are not visable by the naked eye.

Here is an example:

The projectors have cutoffs with a blue colour due to the light spectrum. When you see the lights from far away or going over bumps, it will give the effect of a blue tint but the actual Xenon bulbs are standard 4300k. Basically you don't need to have a high kelvin bulb to achieve the blue tinted look.

The blue cutoff comes from the projectors, period.

All OEM HID bulbs IIRC are 4300k, in accordance with DOT requirements.

and for the hell of it here is my halogen vs oem xenon (4300k)

and notice in the pic above, the blue tint around the light - then below notice the light output... WHITE, not BLUE - the blue cutoff is from the projector lenses
