Why don't my HID light colors match?

Hey this question is open to anybody who may have a possible resolutions. I bought 35 W 8000k
HID lights for my Honda accord 2004. And it seems that the side with the battery the drivers, is a lot brighter and whiter then the right side. Any reasons why this may be I'm thinking because of cheap aftermarket bulbs and or ballasts?

Probably because its a cheap chinese HID kit.

Good kits cost $100 and up. OEM bulbs and ballasts can run up to $500
