GVM Photographic Video Lights Are High Color Rendering Index Beads.
Oct 17, 2018

The LED lamp beads used in the GVM photographic video lights are high color rendering index beads.

The color rendering index reaches 97+, which is the highest color rendering index LED photography light on the market. It is closest to the sunlight, which makes the video photography effect better and restores the most realistic product color.

The ability of a light source to develop an object is called color rendering index, and is a comparison of the appearance color of an object with a reference to the same color temperature or a reference light source (incandescent or painted). The spectral content emitted by the light determines the color of the light source, but the same light color can be made up of many, a few or even only two monochromatic light waves, and the color rendering of each color is also very different. Light sources of the same color have different spectral compositions, and light sources with a wider spectral composition are more likely to provide better color rendering quality. When the source spectrum has little or no main wave reflected by the object under the reference source, the color produces a significant color shift. The greater the degree of chromatic aberration, the worse the color rendering of the color by the light source. The color rendering index coefficient (Kaufman) is still a common method for defining the color rendering of light sources.

The 5500K white light is the 100 index. Others are not 100 as long as it is not white. The deeper the color, the lower the index.


When there is little or no main wave reflected by the object under the reference light source, the color will produce a significant color shift. The greater the degree of chromatic aberration, the worse the color rendering of the color by the light source. The color rendering index coefficient (Kau fman) is still a common method for defining the color rendering of light sources.

The color rendering index of sunlight is defined as 100, and the color rendering index of incandescent lamps is very close to daylight, so it is considered as the ideal reference source. The system is tested with 8 chromatographic standard color samples, and the degree of Deviation of the 8 colors under the test light source and the same color temperature is compared to measure the color rendering index of the light source, and the average deviation value is taken. Ra20-100, with 100 being the highest, the larger the average color difference, the lower the Ra value. Light sources below 20 are generally not suitable for general use.
