Good optics, bad light

Well, my car is fairly new and has headlights with lenses.
The standard light factory is very good, but does not look like much optically flat.
That's why I looked around and decided to go for these lamps, because they seemed despite good optics loud advertising still brighter than standard lamps to be. Since I am much on the night road because my working hours seemed to me more light to be quite useful.

Well, unfortunately I was in terms of luminous efficacy bitterly disappointed. With this light, I felt unsafe and uncomfortable Concentrated night almost, because you have to compensate for the lack of light with attention.
I then times a lamp on standard switched back and that was really much brighter.

The appearance is of course good, if one looks at the car really looks deceptively similar to the xenon. However, one must bear in mind when one goes to the optics must also all other lamps as parking lights, fog lights and possibly also switch the high beams on blue lights ...
If you are looking from the car to the road, the apparent white but suddenly no longer know but already has a very blue sheen, which is why it's probably so dark.

Have now installed the Night Breaker Osram. The make Optically her a bit more, even if there is a slight yellow tinge noticeable. They are at least visible wiser than the standard light and thereby to drive a little more pleasant. And the light output is extreme, incomparable with the BlueTech and still much brighter than the standard bulbs.

Conclusion:
+ Great look

- You have all the lights swap so a really coherent picture exists
- Light seems more blue than white on the road
--- The biggest minus is the very poor light output, had me can not get used to it after three days

Who is to show off and only on the town of can I do think recourse to these bulbs.
Who is more at night and overland or on the highway on the way, I can only advise against these lamps. Here is probably one Night Braker a really good alternative ...
Alone because of the optics gets the BlueTech even 2 stars, more is not indoors in low light performance.
