This video compares brightness of a Chinese XHP70 at 56-5700K vs a CREE XML2 LED at 4300K. You will notice the section about how far you can see with one led vs the other. Light color does come up on several occasions, but again it is to show that the more natural looking color (4300K) which is harder to produce is also very bright since it is in a real CREE LED. 4300K is a pretty close color match to the sunlight from our star.
It is very rare to find Chinese LED's in anything other than very blue hues. 5400-5700K are extremely common in Chinese LEDs. They are color hues produced by blue giants...and our world does not orbit one of those!
