With respect to Jon, I tend to disagree. It is my opinion that H9 projectors fitted with an H7 lens are the best ones available.
H9 projectors have a much bigger reflective surface area, due to the fact that they are detuned HID Projectors. Indeed the H9 bulb base and its mounting in the H9 Projector are very similar to the same projector using the D2S HID bulb. Therefore, retrofitting the H9 with a D2S HID bulb is the best combination.
Also, there are H9 HID kits available too...
