Besides having a wide color-temperature span ranging from 2,300 K to 9,300 K, it also emitted a significantly high
color rendering index, ranging from 74 to 84.4 for voltage increasing from 3.0 to 11.5 V (Figure 3).
As of February 9, 2011, for LED lighting devices with an input power of 25W, a color temperature of 3000K (GW5DMC30M04), and a
color rendering index (Ra) 83 (based on Sharp survey).
Eighty-four precision fitted LEDs provide excellent shadow control and an industry-leading
color rendering index of 97, giving surgeons better tissue differentiation, even deep in the pelvis.
The Sylvania TRU-COLOR[TM] METALARC[R] CERAMIC family of metal halide lamps combines the attributes of conventional pulse starting with innovative ceramic arc tube designs for improved lamp-to-lamp color consistency and a high
color rendering index of 80-94 (CRI).
As with all GlacialLight down lights, the GL-DL10-SM comes in either Warm White (3000K), Neutral White (4000K), or Cool White (5700K) color temperatures all with a
Color Rendering Index (CRI) of 80.
added 80, 85 and 90
color rendering index (CRI) options to its XLamp XP-G and XP-E warm white LEDs.
The larger sphere better integrates light for more reliable testing of a device's photometric and colorimetric performance with measurements of Total Spectral Flux, Luminous Flux, Correlated Color Temperature (CCT),
Color Rendering Index (CRI) and Chromaticity.
* Color rendering, measured on a
color rendering index (CRI) scale of 0 to 100, is the ability of a light source to represent colors in objects.
In fact, the leading color-rendering authority now indicates that the
Color Rendering Index (CRI) may be overemphasized in most applications, and not the best metric for determining the suitability of LEDs for outdoor lighting.
