Although most lamps emit “white” light, this can vary from a cozy “warm” white to a “cold” white according to the “colour temperature” of the lamp. The following chart shows the code numbers used for some of the most popular types:-
| Colour Temp | Colour Code | Designation | Application |
|---|---|---|---|
| 2700 | 827 | Warm White, Extra Warm White, or Interna |
Similar light to “normal” incandescent bulbs, giving a warm “cozy” feel |
| 3000 | 830 | Warm White | The colour of most halogen lamps. Appears slightly “whiter” than ordinary incandescent lamps. |
| 3500 | 835 | White | The standard colour for many fluorescent and compact fluorescent tubes. |
| 4000 | 840 | Neutral White | Gives a more clinical or “high tech” feel. |
| 6000 | 860 | Cool White | Fluorescent or compact fluorescent lamps simulating natural daylight. |
| 6500 | 865 | Cool Daylight
(Pure White) |
Extremely “white” light used in specialist daylight lamps. |
