Super Bright - super fast (broken)

Lamps were with me about 3 months in use - used almost exclusively at night, during the day only in bad weather. After this short period is now a lamp inside black, hence far worse light. A very clear workmanship! Property unfortunately the bill sipped, now trying to settle on what Amazon. The luminous efficacy of the lamp is the way great - I had never been so bright lights. In my lens headlights almost a xenon look. Night trips are very relaxing with this light, therefore I will order again.

Update: The second lamp after another two months now black and the inside, I'm assuming, that this is a very blatant manufacturing defect. Have now again a set of lamps installed and wait and see what happens.

Update 04:08:11
The next set Bosch bulbs is after nearly 6 months also inside blackened and thus unusable. Have the bulbs sent to Bosch and after 2 months get the message that the lights were simply at the end of their service life. That was in such high power lamps now even a very short period. Why they are now inside black, Bosch can not say.
Well then - must be as well. Other high-performance lamps keep no longer with me. However, were the Bosch clearly the brightest.
Conclusion: More Security does not come for free.

Update 01/04/2012: Had between with a new pair of lamps installed, now the first of the lights is to just over 6 months failed. I have avoided in this time to have been turned on the lights during the engine start because again, not to go out in my car, like recently with many other at startup the headlight, but have to cope with the extreme voltage fluctuation. 6 months already better than 3. Next, I'll install a set of Philips Extreme Vision.
