Colour Temperature

Colour temperature is a standard method for describing colours for use in a range of situations and normally expressed in units called Kelvins (K). Note that the term “degrees Kelvin” is often used but is not technically correct. The colour temperature is for descriptive purposes only and does not relate to the actual temperature of the lamp.
