Correlated color temperature (or CCT for short) defines the color appearance of illumination and is measured in Kelvin (K). It tells you whether the light is “warm” (yellow/red) or “cold” (blue). A burning candle has a color temperature of about 1800K (very warm), while a clear blue sky can go above 10 000K (very cold). CCT is not a measurement of brightness or light intensity, however, CCT does impact how bright a light is perceived. The color temperature of a light also has an effect on the production of melatonin in the human body, with colder color temperatures surpressing melatonin creation. Thus, color temperature either has a tiring (warmer CCT) or energizing (cooler CCT) effect, depending on where on the color spectrum you look.
We make most of our lights with a cool color temperature, with a CCT between 5000 and 5700 Kelvin. Over 30 years of field tests with the largest vehicle manufacturers in the world has determined that this span of color is optimal for most applications, such as construction, mining, agriculture, forestry, and material handling.
The illumination is similar to daylight, increasing alertness and reducing eye strain. At the same time, the illuminated area is comfortable to look at for longer durations of time. Visual ergonomics improve when lighting is optimized for the task at hand.
For extreme use cases, we recommend the Scorpius N4402 WARM. This light is calibrated at 2700 Kelvin (warm), and is excellent in reducing overly sharp contrasts, whiteouts (blown-out colors), and increasing overall visibility in the worst possible conditions like thick dust, snowstorms, and heavy rain.
Check out the color temperature at the technical specification of the light. Or, use the filtering system. We have ready-made solutions for the most common segments, and can make tailored solutions for your needs.
