I can't stand the 6500K of LED's. I would not use anything higher than 4300K which is what factory HID's are so might as well just get the factory HID system.

As many others have stated, HID or LED retrofitting is bad advice.
I have used the Daniel Stern-sourced 65w 2100l H7s in many vehicles. They're awesome and they work properly as the headlamp was designed.

Yes "with a lot more light" in all the wrong places. LEDs are just as inappropriate to attempt to shoehorn into halogen housings as HIDs are. They are not capable of being focused, as they are too large in width and do not emit an even 360* sphere of illumination. Most flat face LEDs emit a 120* cone, with higher intensity as you angle directly above the emitter. They cannot fully illuminate the reflector (or reflector bowl, if projector based) in the same manner, and there will be significant changes in the beam pattern, as well as where the highest intensity region of light is.
LEDs typically produce a very even appearing wall of light, with not much light being directed towards the high intensity zone near the horizontal cutoff of the lowbeam. While a massive amount of light near the vehicle feels comforting, and gives the impression of great improvements in the ability to see, it is not useful to see things 50' from you when you really need to see thing 5x or more that distance. I can link to some testing on another forum if you want to see some results in both projector and reflector based lamps.
