CFL/LED Bulb’s Color Temperature sets the “Mood”

Bulb Color Temperature

ENERGY STAR qualified bulbs are available in a wide variety of shades of white light, ranging from yellowish to white to bluish white light, which allows you to customize the mood of your space. Many ENERGY STAR qualified bulbs come in “warm” colors to match the yellowish light of incandescent bulbs, but you can also choose “cooler” colors with whiter or bluer light.

See Energy Star’s link on Color and Mood:

Be careful in checking the color temperature of efficient bulbs you are purchasing.  JouleFool recently ran across an LED bulb that claimed to be in the warm, soft light (~2700K) spectrum but had a bluish tinge to it once installed.

Happy Savings,
