What exactly is a light’s color temperature and what does it mean for your building’s rooms?
Measured in Kelvin units, a light bulb’s color temperature will let you know how close to daylight the room’s lighting will appear. This has an impact on overall atmosphere and comfort for your building’s occupants.
Bulbs with higher color temperatures (4600K or higher) will appear white or blue and more closely resemble natural daylight.
Office spaces typically use lights with slightly lower color temperatures — 3100K-4600K — so that the light appears slightly less white.
Bulbs with lower color temperature (3,000K or less) will have a red or yellow appearance.
It is a good idea to consider the main function of the space that is being lit. How often will people use the area? Is a significant space where important meetings or gatherings occur?
In a common space like a conference room or main lobby, paying attention to color temperature is key for creating a comfortable work environment.
Color temperature & CRI impact work environment
Be careful not to confuse color temperature with color rendering index (CRI).
While color temperature measures how closely to natural daylight a room’s light will appear, CRI measures how many different color variations are seen by the human eye.
While they are different ratings, they both impact overall comfort and work environment; neither should be ignored when looking for new lights for a building.
