kelvins

Other similar claims: 25,000-hour life, or about 17 years if used for four hours a day, and 2700 kelvins, meaning these LEDs are comparable in color to soft white incandescents.

The heat from the fuel rises to a temperature of 3,000 kelvins, and can speed along the tube 10,000 times faster than the normal spread of this chemical reaction.

As for kelvins, a measure of the color temperature, this LED has 2700 and that makes it comparable to a soft white incandescent.

The temperature at the upper boundary of the lens, where the phase transition from perovskite to postperovskite occurs, is around 2,500 kelvins 4,000° F.

At the lower boundary, where the reverse transition occurs, the temperature is around 3,500 kelvins 5,800° F.
