Can you please detail the differences between the different types of fluorescent (CFL) light color temperatures and the best application for each?

Thanks!

Hi Pearl,

Thanks for posting your question.

There isn’t necessarily a better or worse application when choosing where to use varying fluorescent light color temperatures. But one important note is that the higher the number in Kelvin, the truer the colors of objects being lit.

A brief breakdown:

Expressed in degrees Kelvin, this is how we measure things like soft white or daylight CFLs. A pleasant soft white will have a color temperature of 3000K. White light ranges from 4100 to 6000K, roughly equal to midday sun. Higher numbers get increasingly blue.

Lighting color temperatures are generally measured by their corresponding degrees in Kelvin. For example, a piece of steel heated to 2700 degrees Kelvin will burn a warm yellow-ish hue and as the heat increases the color ranges from white (at around 3500K) to blue-ish (at around 5200K+), resembling day light. Just remember, the hotter the flame (the higher the kelvin) the bluer the light, the closer to daylight.

Note: For a traditional designed home and garden, it is recommended to use colors ranging around 2700K (Warm White) and for more modern designs, 4100K or higher.

Can you mix warm white and cool white fluorescent or LED colors in the same room?

Thanks,
