color rendering index

Lights produced so far have a color rendering index of 85.

There is ongoing work in improving the "quality" (color rendering index) of the light.

For a comprehensive review of alternative color rendering indexes see .

These eight samples are employed to calculate the general color rendering index .

Finally, the general color rendering index is the mean of the special CRIs: 51.

LED are better because their colour rendering index is better and also because they last longer.

The ability of a light source to illuminate an object's true color is denoted by its color rendering index.

High-pressure sodium lights yield yellow lighting (2200 K) and have a very poor color rendering index of 22.

The color rendering index allows comparison of how closely the light matches the natural color of regular sunlight.

Developed by researchers at NIST, the measure is a possible answer to the criticism of the widely used color rendering index.

This lamp is a white light source with high color rendering index that sufficiently resembles sunlight to allow good color-reproduction with TV cameras.

Publishing widely used standard metrics such as various CIE color spaces and the color rendering index.

It has a color rendering index of over 90, which makes it suitable for the illumination of artifacts such as The Night Watch.

However, some fluorescents are designed to have a high faithfulness to an ideal light, as measured by its color rendering index (CRI).

Color charts can also be used to assess light quality, as in the color rendering index, where reflectance from a set of Munsell samples are evaluated.

An induction lamp features extremely long lamp life (100,000 hours), energy efficiency, high color rendering index, and a color temperature close to incandescent lights.

The extent to which this phenomenon occurs is related to the light's spectral composition, and may be gauged by its color rendering index (CRI).

Colour rendition For the purpose of distinguishing true tissue colour in a cavity, the colour rendering index (Ra) should be between 85 and 100.

On tri-phosphor and multi-phosphor tubes, the first digit indicates the color rendering index (CRI) of the lamp.

LED lamps have a different spectrum of light compared to incandescent sources, and are made in several ranges of color temperature and color rendering index.

Color temperature and Color Rendering Index (CRI) are the standards for measuring light.

A newer version of the CRI, R96, has been developed, but it has not replaced the better-known R general color rendering index.

If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.

More accurate color rendering: The color rendering index is the ability of a light source to correctly reproduce the colors of the objects in comparison to an ideal light source.

Since the eye is relatively less efficient at detecting red light, an improvement in color rendering index, with increased energy in the red part of the spectrum, may reduce the overall luminous efficacy.
