bought this from someone who bought it then changed thier minds. i think they said it was a 4500K im guessing that means 4300K, IDK. Its rather white as I wanted. in the box: 2 of each: ballast has 2 sided tape: I used my own tape adhesion promoter - no modder should be without this stuff. makes 2-sided tape work like cement. bulb - he adapted the gray part so it will pop right into the reverse hole. in hid vs LED http://www.youtube.com/watch?v=rM8Pkw8CKPc HID both sides http://www.youtube.com/watch?v=NePPR4YrT28
