Super bright white light but unfortunately very short life

Have previously the Philips 12972NGRDLS H7R NightGuide + 50% 2er Kit driven and have now bestehlt me ​​again.
With also the Bosch H7 +90 Plus and I must say that these bulbs are brighter than the Philips.
The brightness and illumination of the road are really enormous, without dazzling.
I can not say anything because I'm going only for 1 month on the shelf.
Unfortunately, now has 2 months have passed and both bulbs are Platt! At a distance of 20 minutes both pears
with a bright flashing finished their work.

Upon request from Bosch you told me:
All lamps with a higher intensity, however, have physically due to the higher spiral load a partly significantly lower service life of standard incandescent bulbs.

That is, it can sometimes even after 2 months the lights go out.
