The speed of light is a constant and temperature doesn't change it

The speed of light is fixed within a vacuum despite the temperature of its surroundings. Kelvin is a temperature scale just like Celcius (or Centegrade), and Fahrenheit. When you asked "when it is below kelvin" you didn't make any sense. Give a value for the temperture on the Kelvin scale next time you ask a question involving temperature.
Anyway, the speed of light, (c) = 300,000,000 (three hundred million) m/s (meters per second) or 186,000 mi/s (miles per second)

As has been stated, "kelvin" is the name of a measure of temperature. Saying "below kelvin" is like saying "below meter". Also, temperature has no bearing on the speed of light in a vaccuum. The speed of light in vaccuum is a tiny bit less than 300 km per second. The speed of light is NOT constant, but like the speed of sound, is dependent on the medium in which it is travelling.

Temperature is meaningless in a vacuum.
Zero Kelvin is the coldest temperature possible, you can't get negative Kelvins.
The speed of light in a vacuum is about 300000000 m/s, or about 186,000 miles/s

The kelvin scale of measurement has no negative numbers

The speed of light is a constant, unlike the speed of sound. Light travels at 300,000 km per sec.
