Mind posting picture of the beam spread on a wall?

also how do you like them compared to other cars with conventional HID systems?

thank you!:)

please also take a photo of the front! I've been considering them, but the steep price aside, I'm not sure I'd like the continuous LED vs the dots on the US spec

The Acura TSX has the best stock headlites I have seen yet.The R 8 could benefit with this type of light.The TSX spreads a beam all around, almost to rear of car Absolutely awesome.R8s' lights ,Led or not...Weaksauce. :)

on the uk v10 I saw, there were multiple led's with a lens suspended a little way in front of it to create the desired beam pattern on the road - this pic shows it well:

do you get something different in the US?

LED headlights on R8V10

Low beam on the right, the two reflectors on the left are high beam




The low beam headlight is a number of LED's focused on a single point and projected by a single lens assembly




The high beam is of a different construction and is made up of LED's with beams projected by two metal coated reflectors




They work very well, but don't seem to be any better or worse than Xenon HID (I will try to get a night shot done and posted). But, they come on instantly (compared to a short delay for HID), they run much cooler and they use much less power.

Are they worth paying for as an option ? No ! It's just Audi showcasing a world first on its flagship car.

I prefer the v8 drl dots to the continuous on the led's.
Agreed

Thanks for those pics. I agree, I don't think they're worth that price tag. The smoked tails with amber turns are though :D

Sorry for the confusion!
Thank you very much R8 england, you're posting the exact pictures I need and I can't wait for the night time shots!!

If you haven't taken them yet, do you mind if you take the pictures similar to these:
Low Beam: (doesn't need to be in-car because i want to see the width of the beams projected on the wall)


And of the High Beams in the similar fashion


other examples:

I have a question R8 England after seeing your pictures over again.

In the Left headlamp on the lens-part, is that a black piece covering over the top part where there's a piece exposed? On the Right headlamp I don't see a little black cover. What do you think is the purpose of this?

As a led and optics fanatic I can add that in the low beam set-up, described by R8 England above, the 3 leds are first individually collimated by 3 TIR (total internal refraction) optics. These focus 3 individual beams onto the curved lens which is actually the centre part of an aspheric lens, this then produces the beam.

Optically, a very clever system!

Although the system will run cooler (all the main leds are mounted on large heat sinks) I am not convinced they consume any less power than a modern HID set-up.

yay another LED/optics fanatic :)

The lowbeams themselves consume 50 watts per headlight (in another article they said 44 watts though). More than HID's (45 watts) but less than Halogens (55-68 watts), but they're improving! I think when they emphasize LED's eating less energy they imply the DRL's since they only consume 6 watts in the R8

I'm just interested in pictures of the light distribution and cut-offs because all of the data is from reading and im a guy who needs to see it =P

It is the angle of the light or shadow. The semi-circular glass lens on the low beam is purely a lump of glass, there is no cover on it and nothing is black.

I will take some night time pictures against a wall for you.

Ti-Mike: LED is standard on V10, but is an (expensive) option on V8.

As regards brightness, you've had your V10 longer than I have, and I haven't used mine much at night. Perhaps my eyesight is going, but if you believe LED's to be brighter, then I accept your judgement !

the issue is very easy to explain......the lights are much much brighter and respond much quicker and the cut off is razor blade sharp and this is the point.
As the lights on the R8 are very low and the cut off is very sharp, you have the impression that you have less light or your light adjustment is to low....with the little diffusion of the Xenon the light seems to be better distributed......
