What CFL lamp colour should I choose?
The following three lamp colour options are available to suit different lighting requirements: Warm White (2700K) for bedrooms and other areas that require a more intimate or ambient atmosphere Cool White (4000K) for lounge rooms, and other social environments where a bright light is unnecessary Bright Daylight (6500K) for task areas in home offices and work spaces that require a brightness similar to the outdoors The higher the Kelvin (K) rating the bluer the colour gets. Lower Kelvin-rated CFLs have more yellow and are similar to the light colour of an incandescent globe. The Kelvin rating only refers to the colour of the light emitted, not the brightness, and different colours should be used for different situations as listed above.
