(See COLOUR RENDERING INDEX)
Colour rendering index. A number used for rating light bulbs on their ability to accurately reproduce color on scale up to 100, where 100 is equal to sunlight.
Color Rendering Index. Measure of the degree of color shift objects undergo when illuminated by the light source as compared with the color of those same objects when illuminated by a reference source of comparable color temperature.
Color Rendering Index. Measured on a scale of 0-100, where a light source with 100 CRI is best at producing vibrant color in objects. A higher CRI rating typically denotes a higher quality lamp.
rating – Abbreviation for Color Rendering Index. Represents a numerical rating (95 being the standard) for overall brightness and evenness of a viewing light field, as in a light table.
Color Rendering Index (CRI) is a term used to describe the extent to which an artificial light source is able to render the "true" color of objects as seen by natural outdoor sunlight which has a CRI of 100. No artificial light source has a CRI of 100. The closer the CRI of a lamp is to 100, the more "true" it renders colors. Generally, a lower CRI indicates that some colors may appear unnatural when illuminated by a lamp.
Color Rendering Index. A scale used to measure how well a lamp illuminates an object's color tones as compared with the color of daylight.
Color rendering index. A method for describing the effect of a light source on the color appearance of objects being illuminated, with a CRI of 100 representing the reference condition (and thus the maximum CRI possible). In general, a lower CRI indicates that some colors may appear unnatural when illuminated by the lamp.
COLOR RENDERING INDEX. A scale of the effect of a light source on the color appearance of an object compared to its color appearance under a reference light source. Expressed on a scale of 1 to 100, where 100 indicates no color shift. A low CRI rating suggests that the colors of objects will appear unnatural under that particular light source.
Color Rendering Index. The CRI refers to how close the spectral curve of the light approximates that of the sun in a percentage, with 100 being the closest. Any bulb with a CRI rating over 90 is considered a full spectrum bulb.
Color rendering index. The Color Rendering Index (CRI) measures the effect a light source has on the perceived color of objects and surfaces. High CRI lights makes virtually all colors look natural and vibrant. Low CRI causes some colors to appear washed out or even to take on a completely different hue.

Color Rendering Index. A measure of the degree of color shift that objects undergo when illuminated by a lamp, compared with those same objects when illuminated by a reference source of comparable correlated color temperature (CCT). A CRI of 100 represents the maximum value similar to the light of the Sun at midday. A lower CRI value indicates that some colors may appear unnatural when illuminated by the lamp. Incandescent lamps have a CRI above 95. The cool white fluorescent lamp has a CRI of 62; fluorescent lamps containing rare-earth phosphors are available with CRI values of 80 and above.
Color Rendering Index. An international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer colors generally appear. CRI ratings of various lamps may be compared, but a numerical comparison is only valid if the lamps are close in color temperature. CRI differences among lamps are not usually significant (visible to the eye) unless the difference is more than 3-5 points.
Color Rendering Index. Color rendering is the ability of a light source to produce color in objects. The CRI is expressed on a scale of 0-100, where 100 is the best in producing vibrant color.
Color Rendering Index (CRI) is a term used to describe the extent to which an artificial light source is able to render the "true" color of objects as seen by natural outdoor. The closer the CRI of a lamp is to 100, the more "true" it renders colors. Color rendering is measured on an index from 0-100, with natural daylight and incandescent lighting both equal to 100. Objects and people viewed under lamps with higher color rendering indexes generally appear more true to life.
Colour Rendering Index measures the ability to distinguish different colours. The higher the Ra, the easier it is to see the difference. Measured in Ra.
Color Rendering index. A scale for the effect of a light source on the color appearance of an object in comparison with the color appearance under a reference light source. Expressed on a scale from 0 to 100, where 100 is no color shift. In general, a low CRI rating indicates that the colors of objects will appear unnatural under that particular light source.

Color Rendering Index rates a light sources 1-100 wheel natural sunlight is 100.
COLOR RENDERING INDEX. Indicates the color closest to the sun as available in the lamp. The sun = 100.
Color Rendering Index. A number that indicates how natural the color of items will look under a particular light, with 100 being as clear and precise as daylight. When purchasing CFLs, you should look for a CRI of 80 or higher.
Color Reversal Intermediate, a duplicate color negative prepared by reversal processing.
Color Rendition Index. Measures the way a light source renders color. The higher the index number, the closer color resembles how it appears in sunlight.
Color Rendering Index. An international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale), the better colors appear, CRI ratings of various lamps may be compared, but a numerical comparison is only valid if the lamps are also rated for the same chromaticity or color temperature. A measurement of the color shift an object undergoes when illuminated by the light source, as compared to a reference source at the same color temperature. Color rendering is measured on an index from 0-100, with natural daylight equal to 100.
Color Rendering Index. A measure of the color shift created by artificial light. Color rendering is measured on a scale from zero to 100, with natural outdoor light having a CRI of 100. The higher the index, the more true to life colors appear".
Color Rendering Index; a quality of the light; a measure of the lamp's ability to "render" colors accurately
Color Rendering Index. An international system used to rate a lamp's ability to render an object's true color as compared to sunlight using a scale from 0 to 100 with a higher numerical value indicating a better color match. A value of 100 would be equivalent to sunlight and 0 would indicate that colors are not distinguishable from each other. Numerical comparison, using the CRI, of different lamps is only accurate if the Color Temperature Index values are similar. Differences of less than 5 points are usually not visible to the human eye. A CRI above 80 is required for color matching tasks. When selecting lighting for an area, it is important to consider the degree of color recognition that is required to complete tasks. A low CRI value makes it hard for humans to differentiate between colors.
Color Rendering Index. A measurement of the color shift an object undergoes when illuminated by the light source, as compared to a reference source at the same color temperature. Color rendering is measured on an index from 0-100, with natural daylight and incandescent lighting both equal to 100. Objects and people viewed under lamps with a high color rendering index (CRI) appear more true to life.
Corporate reputation index
Color Rendering Index. The ability to render colors to a standard.
Corporate Responsibility Index - a voluntary benchmark of responsible business practice created by BiTC
COLOR RENDERING INDEX. A rating method by which fluorescent, or any other light source, is evaluated according to its ability to impart color to colored objects, with natural outdoor light having a CRI of 100. Cool White has a CRI of 62, Vita-Lite has a CRI of 91.
COLOR RENDERING INDEX. A measure of a lamp's ability to render colors accurately. The scale ranges from 1 (low pressure sodium) to 100 (the sun). A cri of 85 is considered to be very good.
Color Reversal Intermediate. A particular kind of reversal (original) film which can be struck directly from another negative, without going through an intermediate positive stage, such as with an I.P.
Color Rendering Index. This is very important as it tells you how your light will render, or portray, the accurate color of everything it illuminates. The CRI runs from 1 (for Low Pressure Sodium lamps) to 100 (for the Sun). A CRI somewhere in the 80's will give you good and true color portrayal.
