Luck you. I used to own a non European H4 Hi/Lo set, and the bulb blew 3 times within a year. Also, the genuine/branded European HID (BMW, Benz) produce around 3200 lumen, however, some after market only around 2700 lumen and not build according to the standard. If they try to make it produce up to 3200 lumen, it will cause too much glare from the reflector and easily blow up. Lots to think about to select the right one and sometimes don't mind to pay a bit more to get the right product, right "K", and last longer.
