The reason I'm asking is I have a complete High Performance Bulb 6000k high-powered kit.

A kit which has worked flawlessly for nearly 2 years and counting, with the exception of that 12 LED dome panel light, which never really worked.

I had gotten a T10 peanut bulb around 2 years ago, which works beautifully, but has a pale white color in comparison to the rest of the lighting, which is more of a cool blue white, which I love.

Today I located two different pairs of T10 6000k LEDs, guaranteed to work with BMW blah blah blah... Korean quality blah blah blah...

I guess the question is, is the 6000K an "industry-standard" if you will when It comes to LED lighting, or is there a good chance it could be a shitty pale yellow white just like the one that I have?

I guess worst case scenario I'll be selling quite a few different LEDs in the for sale section, so be looking for them folks LOL

For comparison, map lights versus ugly pale white blinding LED dome

Short answer yes, longer answer it may very slightly by manufacturer. 6000k should be bright white with a slight hint of blue

Good- because I think these bulbs were around 4 to 5000K.

I guess we'll find out, I have three different ones to test soon! Will keep everyone posted.

6000K is a nominal color on the CIE 1931 color chart that falls right on the black body curve. LED Manufactures will product LED's and they are rated into various color groups that are normally pretty close to this black body. Each manufacturer however is different and each LED can be slightly different too.

Cree for instance sells a group of LED's with a color of " 6500K, however there could be a variation from 6000 - 7000k within that range.

At 7000K you will start to get a slight blue hue.

besides the color, you also have to consider the brightness in lumens and the color rendering index (cri). in short if you really want the colors to match, i would suggest using the exact same bulb

6000K most certainly varies from manufacturer and even within the same manufacturer at times depending. Some may give off a more yellow hue and others a more blue hue. It is just the nature of LED manufacturing processes, quality control differences as well as the led emitter/chip used, output, ETC. Although with high end LED manufacturers those variations tend to be small. Of course, it all just depends really.
