Color temp is measured in degrees Kelvin. The higher the number, the closer to blue/white, the lower the number, the closer to red/orange. 2700K is a nice place to land.

Yellow, warmer light color (2500K-2700K), on the other hand, cues warmth and relaxation. But that’s not because yellow light comes from the sun.

Turn it off, then on again, and the bulb delivers 800 lumens but at a quite cold 5000K color temperature. Turn it off and on a third time and the bulb dims to 80 lumens of very warm 2200K light.

With a temperature range of 2700K to 6500K, these smart white bulbs run the gamut. They can be dimmed to fit the mood, but their maximum output of 800 lumens makes them perfect for any task.
