However, the shelf life is a disaster!
I had a first lamp set purchased and installed in November 2014. End February 2015 were both lamps broken in quick succession.
After only 3 months and about 150 hours !!! That's a No.
My previous Osram Standard lamps have loosely held for a year.
The high-performance lamps have a shorter lifespan than standard lamps is well known, but are for the Osram Night Breaker at least 450 hours and not 150 hours.
However, I have now ordered another set, because I am convinced by the light.
Should this rate also give up after such a short time, I'll look around for alternatives, however.
If the second sentence should now have a better life, I will also like to change my vote on 4-5 stars.
But we are now waiting until times.
