Correlated color temperature (CCT) is a scale of the color of a light source, the latter being defined by chromaticity coordinates when heated to a particular temperature. It is measured in degrees Kelvin (K). The CCT rating for an LED measures the warmth or coolness of its appearance. The...
Mechanical measures of LED light quality such as the Color Rendering Index (CRI), the Color Quality Scale (CQS) and the Metamerism index (MI) are meant to rate a lamp’s ability to produce light that will faithfully reveal the colors of various objects as they ...
It could be any of the following issues, to name a few: appearance, color quality, controllability, emphasis or lack thereof, flicker, harshness of shadows, lack of shadows, illumination levels on horizontal and/or vertical surfaces, luminaire placement, proportions, and/or scale. Any of these...

By applying mesopic luminous efficiency functions, there are significant differences in the luminous efficiency scale between LED light sources with different correlated color temperatures [5]. The visual performance for night-time driving conditions was investigated by carrying out three visual tasks, ...
Thus, while the Grolux light has a purple glow with a slight red appearance, the Grolux WS is white in appearance with a CCT of 3700 K. Nevertheless, this second technology has no relevant presence in the scientific literature concerning in vitro plant tissue culture procedures. During the ...
Grayscale multiplication technology The technology raises contrast ratio of low grayscale image by 64 times to solve problems such as mosaic and vignetting, providing delicate image transition. Automatic brightness adjustment With the help of a light sensor, the LED screen enables automatic brightness ...
