A number used for rating lite bulbs on a scale up to 100, where 100 is equal to sunlight.
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.
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.
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.
A measurement of the amount of color shift that objects undergo when lighted by a light source as compared with the color of those same objects when seen under a reference light source of comparable color temperature. CRI values generally range from 0 to 100.
(CRI) - Measures the color rendering ability in comparision to natural sunlight
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.
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.
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.
A scale used to measure how well a lamp illuminates an object's color tones as compared with the color of daylight.
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.
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.
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 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.
Indicates the color closest to the sun as available in the lamp. The sun = 100.
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.
The CRI is a measurement of the effect a light source has on the perceived color of objects and surfaces. High CRI light 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.
Light bulbs offer a varying range of attributes that can produce different light outputs and qualities. The color rendering index (CRI) provides a base of mesaurability to render color accurately and consistently.
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 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) generally appear more true to life.
(CRI) This is an international system used to rate a light's ability to render true colors. The higher the CRI (based on a 0-100 scale), the better the colors appear.
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.
A term used to describe the extent to which a light source is able to render the true color of objects. Incandescent is used as the base reference of 100 CRI. Compact fluorescent lamps are graded at 82-86 CRI, which Is considered high quality color rendering. CRI is a more important consideration for retail lighting design than It is for office lighting.
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.
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.
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.
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; a quality of the light. It is a measure of the lamp's ability to `'render" colors accurately.
