I have a Mercedes B class, I had a Philips X-treme power and I wanted to test OSRAM Night Breaker more. Well I was very disappointed, the luminous flux is not homogenous and little power compared to Philips, the difference is obvious. the only positive is that I no longer dazzled users arriving in front of me, with Philips, I often had the lighthouse calls. For life, I can not say, since I've had less than a month.
