Well, I know with HID's, that 4300k are stock OEM which are similar to halogen in colour. 5000k are white. Anything over that, you lose light output. I've converted all my interior to LED except the passenger map light. Reason being, if a passenger wants to put the light on, it gives enough light without being too bright when driving at night. Driver maplight is LED so is there if I need it. I've also put in a row of 5050SMD's across the top back of the lift gate. The stock one, even with LED isn't bright enough to see well in the back.
The beatings will continue until attitudes improve!
