Light bulb colors are measured in kelvins, the scientific unit of measurement for thermodynamic (heat) temperature. A lower ...

As you move from lower to higher Kelvin ratings, the color temperature changes to create different color light. <2000K-2600K (Warm White): This creates a warm and inviting atmosphere. Most ...

This is called a "temperature ... The lower the Kelvin rating, such as the common incandescent/tungsten bulb, the warmer, softer and more yellow the light. The higher the K number, the cooler ...
