Bought 2 sets of 4300k 35 watt a few months ago. They all look green. They exchanged 1 set with 5000k but they look blue and are not really that bright (supposed to be pure white). Request to exchange my other 4300k and they won't do it because it's over 30 days. The reason it's over 30 days is because it took them over 3weeks from the time I send my old one to get the new set. It also took a few days to email each other. Also my other set of the 4300k only work once (to test it after the installation), and doesn't work after that. So , now I'm stuck with no working kit. The reason why I bought from ddm tuning is because they were recommended from a few guys I know. And one of the people also had a problem with the shipping time. I would never buy from ddm tuning again or recommend to anyone.
