They "perform" the same since they both run at 35watts. 4300K HID will always be brighter then 6000K HID. 6000K is like 10-15% dimmer then 4300K if you want to get technical. 8000K is even worse its almost like 30-45% dimmer then 4300K.
His is D2R HID which is 2800 lumens if your is a D2S then you'll be at 3200 lumens. Also HID does color shift that is why 4300K does get a bit bluer over time. Also it gets a bit dimmer over time. If both HID was brand new his would be brighter then yours.
what's the difference in D2R and D2S and how do you know what kit you have? what kit is better?
