Default dumb question about xenons: what does the "K" stand for when referring to 4300k, 5000k etc.

I've always seen this but never thought about what it stood for. I've heard it been called Kronas? or Kilowatts? What's the definitive answer?

Thanks!

Default Degrees Kelvin

It's what's called a color temperature. It is also used in TV sets for example.

that would be a pretty dim light - standard automotive headlights rate up to 50,000 candlepower

Default Kelvin A temperature scale in which zero occurs at absolute zero and each degree equals one kelvin.

Water freezes at 273.15 K and boils at 373.15 K.

from the dictionary

Default misconception:

That does NOT mean the bulbs burn at a temperature of 4300K, or 4027C, which would be a whopping 7280 Fahrenheit.

It means that the color is equivalent to light with that equivalent energy. Light energy (which obviously is in direct relation to heat) has a broad spectrum, expressed in Kelvin. Sunlight is about 4300K, halogens *(yellowish, leaning to the red end of the spectrum) are lower, xenons *(bluer) are higher in "color temperature"
