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.
A high color rendering index
reduces the burden on the eyes and positively affects the performance of employees.
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.
It is important to note that in the luminaires of the ULT-Q218 series high-quality diodes are used, which ensure the efficiency of 90Lm / W and a high color rendering index
(RA = 80).
