Just wanted to know the exact bulb BMW use for their HIDs in the E70.

Is it Philips, Osram etc..... does it differ for various regions in the world.??

Or does Spartanburg send out all HID x5s with the same brand model bulb??

Also what is the exact "K" & wattage rating....

4300, 4350, 4500k ?????
