I bet it is over 6500K...I had 6500K and I felt it did not light up the road well, especially in the rain. Only on pitch black roads were they better than factory. For truly better visibility, I suggest between 4300K and 5000K. I have 5000K on the Crossfire right now and I love them. They are ever so slightly more blue than factory HID's. You really have to stare to notice the difference.
