That color temperature has a precise place on what is called the Kelvin Color Temperature Scale.Most colors you will deal with have values of between 1,000K and 10,000K.A candle flame will be around 1,500K, tungsten bulbs are about 3,200K, noon daylight is approximately 5,500K, and a clear sky has a color temperature value of 10,000K or more. The Range of Color Temperature. The three primary types of color temperature for light bulbs are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). It is measured in degrees on a Kelvin scale (K) and typically ranges from 2700 – 5000 degrees Kelvin. A good point of reference is that the sun at midday measure 5780 Kelvin. A light bulb with a brightness of 450 to 800 lumens and a color temperature of 5000 to 6500 Kelvin is a good choice for a reading lamp. Bedrooms: warm white lights can provide the relaxed, peaceful mood required in a bedroom.Color temperature from 2700K to 3000K is suggested. If you look at that color temperature on the scale of color temperatures, you’ll find the light is beginning to touch the edges of the bluish range of light. For tasks like reading, you should use cool white light. This equates to a 10- or 15-watt CFL bulb, an 8- or 12-watt LED bulb or a 40- or 60-watt standard bulb. The higher the Degrees Kelvin, the whiter the color temperature. Light bulb color temperature is represented in the unit of absolute temperature, Kelvin, noted by the symbol K. Household fixtures are commonly found in color temperatures on the Kelvin scale of 2700K (warm incandescent), 3000K (warm white halogen) and 3500K (household fluorescent). between 4700 and 6500 kelvins. As an ex-photographer, my Kodak technical manuals roundly recommend a viewing light of a colour temperature that matches average "daylight," i.e. LED Color Temperature Scale Tips for Every Room. This yellows the screen and provides a warmer look. Drop the Color Temperature (Target White Point on Mac) into the yellow. For a lot of people, it also makes it easier read for long periods of time. Its easy-on-the-eyes and doesn’t cause eye strain or stress. What Color Temperature Lighting is best for Schools? Ever wonder what type of lighting would be optimal for high concentration tasks such as reading? In our previous post on color temperature, we gave discussed the optimal color temperatures for certain activities and the possibilities of LED color tuning . Also, many of the reading lights on the market are daylight temperature, as the color provides great contrast between black type on white or off-white paper, making it easier on the eyes to read.” Kelvin Color Temperature Scale chart. It is the most suitable color for night reading on the bed and sleeping. Kelvin Color Temperature Scale Explained The Kelvin color temperature scale is used to describe the way various light temperatures appear visually. The best color of light for reading at night is 3000K; it is a color temperature that has a warm tone or a yellowish color. How to Choose the Right Kelvin Color Temperature.
