5000K-6500K Daylight LED White 2835 SMD LED 60-Degree

What doed 6000K mean for LED lights? 

As we know, there will have kinds of white LED when we talking about white SMD LED or White Through-hole LED. Some white LED looks bule-ish and some white LED looks yellow-ish. That's the color temperature of white LED. Normally we name those blue-ish white LED as cool white LED and those yellow-ish white LED as warm white LED. People also have another unit to represent the color temperatre: Kelvin or K. 6000K are the one that marked between the white-ish and blue-ish side of graph. It will also named as cool white color.
