VIVID COLOR AND NATURAL WHITES
Color rendering is measured by TM-30 Rf while white rendering is measured by Soraa's internally developed whiteness rendering index Rw. Both Rf and Rw require a smooth spectrum similar to natural light. Because of our full spectrum technology (violet to deep red), we're able accomplish this with ease.
Soraa VIVID Color™
The Spectrum of natural light (shown below, sunlight with a CCT of 5000K) is closely matched by Soraa VIVID Color technology. The four peaks correspond to the violet pump and light from the three phosphors (blue, green red). Which means every color, violet to deep red render as pure as possible.
Soraa Natural White™
Whiteness in natural light is provided by ultra-violet radiation which excites the fluorescing agents of white materials — but UV radiation is harmful and undesirable in LED light. We solve this by replacing UV radiation with harmless violet light, which enables the same whiteness rendering as natural light.
Natural light (above, halogen lamp at a CCT of 3000K) creates whiteness by exciting fluorescing agents with UV radiation. Soraa's spectra use violet light instead to render whiteness without the harmful effect of UV.
THE PERFECT RECIPE
Because we have the addition of violet light, we reduce the color rendering slightly, but we make up for that with whiteness rendering. All Soraa VIVID lamps and luminaires are designed to optimize this trade-off creating the best possible combination of beautiful color and infinite whites.
RICHER COLOR WITH SORAA SNAP ENHANCE
An important point of TM-30 is that while colors can be rendered true, they can also be made more saturated to enhance an environment or given object. TM-30’s Rg index and color accuracy graphic help quantify this effect.
Harnessing TM-30 and studying color preference, Soraa has developed a lamp and directional luminaire accessory we call Snap Enhance which increases the saturation of colors while maintaining the quality of light which includes lights chromaticity and accurate rendering of whites.
