    Yes.
4000K-4200K is the brightest color temperature in my honest opinion.
blue bulbs over 4500K are poor at lighting anything.

I also just replaced my OEM Osram D2S 66040 with the newer 66240 after 1 old bulb died and the other one was yellowing to the point it was quite noticable.  It's best practice to replace them in pairs anyways.  

I also didn't want the CBI versions.  They just look way too blue and makes thing look fuzzy at night.  The 4300k temp gives things a nice contrast so you notice movement before you actually see the object clearly.  That give you time to react.

I also read the colour temp doesn't stabilize until after about 20 hours of use.  I haven't noticed any changes after about 5 hours, so maybe that's with old technology.

Yes... you are right. higher color temperature bulbs emit fewer lumens than lower color temperatures

I would love to get a pair.
Are there any good places in Hong Kong? Or should I get them from US-Amazon instead?

Thank you for your suggestion.
I have tested my eye sight and they are pretty good.
However, the factory HID luminaire produce very poor projection it only covers about the first Arrow to the stop line before zebra crossing, while generate plenty of glare to other cars.
These photos are taken after replacing the luminaire on my car.

    Where did you buy your CBI?
The reason I didnt get CBI is because they are too blue for my taste.

My camera photos doesnt show it, but the NBU D1s are indeed more yellowish than my factory HID.  Thanks to more red in the spectrum, I think the CRI has improved and things become more colourful.
