Let's keep this lens change in perspective.  The original change came 
about because of broken lenses in the DOT lamps due to Colorado road 
rash.  ( Maybe it was Canadian or AlCan highway road rash.) The 
alternative was a complete assembly at $435, so finding that the euro 
lens fit was a stroke of genius.  Then, it allowed access to the 
interior to clean reflectors and projectors.  If you can see through 
the exterior lens of a 10 year old light, you will see the haze on the 
projector lens.  Then the Kansas road rash (Sandstorm) issue was 
addressed by also changing those  badly pitted and sanded OEM lenses 
with the euro lens for less than $50 each.
The idea of changing lenses was economic, not for some superior light 
output through the euro lens.

You can look at the lens covers and assume that the lack of fluting on 
the euro high beam could result in less focusing from the fresnel 
effect, but I don't hear any complaints from daily (or nightly) users, 
or the many european drivers.  I only saw improvement in the low beam 
from cleaning the projector lens and eliminating the light scattering 
from the badly pitted lens covers.

I can't illuminate the 9012 area, but lumens don't lie.  Now, I can say 
HID kits are the best old fart automotive improvement ever made.

Tom,  '95 S6, Thats my .02 euro on this.
