I'm pretty sure that this is the only HID ballast/bulb that anyone has used in a Mag. EDIT: Most commonly used. I think its the same parts that Mac used in his run. You can buy the light together for $115 then take it apart for the needed parts. Thats the cheapest way.
These are 13 or 14 watts. Same as what Mac's put out.
I'd love to try it out, but its just a little to risky for my back pocket.
