at people that buy DDM. It's all crappy quality; a lot of aftermarket stuff really is.
There's a certain ingredient that determines the light output, color, and quality of the bulb: salt. Engineers (zomg DDM and Chinese knockoffs, do you know who they are?) carefully use the current amount of salts, and type to perfect the best bulb.
This is why OEM always wins. No aftermarket bulb has done that. Morimoto says otherwise; pretty good quality, but quality control is ****ty and I've experienced it.
So no, just no to aftermarket DDM garbage. You go to different aftermarket HID websites and their color advertisements are far from the same to others. Some say 6000K is pure white, while other sites say 10000k is white with a slight hint of blue.
