What is color temperature?
- Color temperature is a way to describe the light appearance provided by a light bulb (lamp). It is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000.
- Typically, commercial and residential lighting application Kelvin temperatures fall somewhere on a scale from 2000K to 6500K.
- A light bulb’s (lamp’s) color temperature lets us know what the look and feel of the light produced will be.
- At the lower end of the scale, from 2000K to 3000K, the light produced is called “warm white” and ranges from orange to yellow-white in appearance.
- Color temperatures between 3100K and 4500K are referred to as “cool white” or “bright white.” Light bulbs (lamps) within this range will emit a more neutral white light and may even have a slightly blue tint.
- Above 4500K brings us into the “daylight” color temperature of light. Light bulbs (lamps) with color temperatures of 4500K and above will give off a blue-white light that mimics daylight.
