Colour Temperature of Compact Fluorescent Light Bulb
The colour temperature of a light source is defined as the light colour that corresponds to the temperature of a standard radiator (black body radiator). It is expressed in kelvin (K). The colour temperature of a lamp gives us an idea of its light colour. The light colours or colour temperatures of compact fluorescent bulbs are deter-mined by the composition of the phosphor coating on the inside of the tubes. It is possible to produce white light with very different colour nuances:
- Warm White = under 3300 K
- Cool White = approx. 4000 K
- Daylight = over 5000 K
