Previously held my Osram Night Breaker least 3 months to a year .. now was a bulb that was installed shortly before installation of this part already on January 27th over. That's less than 2 months. The "protection" has been installed on about 14 December 2014. Now I 'm not to cut so my judgment after a pear and most continue to maybe it was also a failure on the part of Osram.
