Color Temperature and Kelvin

Color temperature or CCT (Correlated Color Temperature) represents the color of white light, describes the warm/cool characteristics of light according to its color, ranging from the orange glow of a candle to the bright blue light of the sun. Color temperature has nothing to do with physical heat, while has an important applications in lighting, photography, videography, publishing, manufacturing, astrophysics and other fields. The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that light source. In simple terms, it measures what color of white light is created when a black metal object, like a iron is heated up to a specific Kelvin temperature.

The Kelvin scale goes backwards: the lower color temperature(candlelight), the warm light( or more orange/yellowish), the higher color temperature and the cooler light( or more blue). Most lights have color temperatures between 2700K and 6500K, and we custom manufacture any specified CCT such as 12000K or 2000K.

Warm White(2700K – 3500K)

  • Living Rooms
  • Bedrooms
  • Dinning rooms
  • Resturants
  • Social gatherings
  • Rooms decorated in earthy tones (reds, oranges, and yellows)

Lights with color temperatures between 2700K-3500K are considered “warm.” Warm light is standard in most homes because it strengthens the reds, oranges, and yellows commonly used in residential color schemes. Warm light is often used in bedrooms or living spaces,dinning rooms or any other places to create a cozy atmosphere since it’s softer and help people to relax. It is also often used for general lighting because people tend to look better in warmer-toned light.

Natural White(4000K – 4500K)

  • Kitchens
  • Bathrooms
  • Work places
  • Rooms decorated in airy, fresh hues (blues, green, whites)

Natural white light (4000K-4500K) is more common in homes decorated in blues, greens, whites, or other calm hues that higher color temperatures tend to accentuate. In contrast to warm light, cool light creates an energizing and refreshing mood – the reason many people prefer it in studies or home offices. Cool white light makes imperfections and color variations between objects more apparent. It is useful for applications like makeup lighitng or even general lighting in rooms where cleanliness is imperative. For these reasons, even when cool light isn’t used throughout a home, it typically appears in kitchens(under cabinet lighting) and bathrooms(bathroom lighting). These color temperatures are also ideal for outdoor lighting and security lighting. For accent lighting, intensive projects that require plentiful light and for reading, you might opt for even cooler, daylight-strength color temperatures of 5000K to 6500K. Read blow:

Cool White (5000K – 6500K)

  • Basements
  • Garages
  • Offices
  • Labs
  • Commercial and industrial spaces

Cool white (5000K-6500K) are called daylight colors which appear blue-white. Meant to simulate the color temperature of a bright sunny day, cool white light is a bright white light that appears almost blue in color, described as being harsh on the eyes, so it is not often used residentially. But when it is, it usually appears in basements, garages or home offices. Outside of the home, the cool white light is commonly used in museums, jewelry stores, showcase windows, and hospitals where your workers could be more alert and at their most productive.
