Well to make a long story short: I have tried the Philips X-treme + 100%, I have tasted the Osram Night Breaker. And none of these 2 ("Premium") lamps comes to the light output of the Bosch ran.
The light is very even, brighter and whiter than in a normal lamp. They also light up a little further (here each his headlamp setting should be checked once in the workshop, even mine were set a little too deep from the factory).
A slight yellow tinge is still present, but that is to get over.
All in all I can really recommend the Bosch that are really worth the money!
In addition, they have won a test recently. Therein the Bosch have been tested as H7, as well as H4 convince!
