It is the ratio of luminous flux (in lumens) to power (usually measured in watts). Depending on context, the power can be either the radiant flux of the source's output, or it can be the total electric power consumed by the source 2.What is CCT?The spectrum of light,higher color temperatures (5,000K or more) are called cool colors (blueish white); lower color temperatures (2,700–3,000K) are called warm colors (yellowish white through red). 3.what is the full name of CRI?The color rendering index (CRI) (sometimes called color rendition index), is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. Light sources with a high CRI are desirable in color-critical applications such as photography and cinematography 4.what is luminous flux? luminousflux is the measure of the perceived power of lightThe SI unit of luminous flux is the lumen (lm). One lumen is defined as the luminous flux of light produced by a light source that emits one candela of luminous intensity over a solid angle of one steradian.
