Hi Terry -

Physics 101. A theoretical black body is absolutely black at 0 degrees Kelvin. When heated to glowing, at 5000 degrees Kelvin it emits the spectra that color standards folks have defined for comparative viewing. So the answer is. . . 5000 degrees Kelvin.

Kelvin is just another reference such as Fährenheit or Celsius/Centigrade. The difference of course is varying 0 degree reference points for each system as well as varying increments for each degree change.

- Jon



 if I say "5000K", do I mean 5000 KELVIN or am I REALLY saying 5,000,000??
