Once you get over 5,000K (Color Temperature) your light starts looking a little blue. This isn't a bad thing - lots of leds are sold at 6,000K. Color Differences of LED Lighting - 2.7K, 3K, 4.3K, 5K, 6K
"K" in this situation stands for "Kelvin", not "thousand". It's a unit of temperature, just like C or F. For example, 6,000K = 10,340F Color temperature - Wikipedia
