davesupra, I did get the 6K - cool white option.
Keep in mind that there isn't much play with the adjuster, but it is a visible change nonetheless IMO. I aimed my car at my garage door while I was installing so that I could see the difference and while making adjustments. No fitment issues at all. All the tabs lined up and locked in place with a simple twist.
With the '13 SFS, there is also ample space to work behind the housing to allow you to remove the dust cover and get the bulb in. There is also enough room in the housing to accommodate the bulb and cooling fan and still get the dust cover back on.
I ended up replacing all my lights - low & high beams + fog lamps - so that it's all uniform, and matches up nicely with the OEM LED 'eyebrow'
