I bought a 5000k HID kit from HIDextra last year and I just bought 6000k HID bulbs from the same company. I want to know if I can use the same ballasts that I currently have. Are the ballasts the same no matter what bulb rating? I know that the ballasts that HIDextra sells are only 35 watt. I've done some research on this topic and I've got mixed answers.
