Lumicrest specializes in High CRI LED lights. That means CRI 95+,
The Lumicrest Apturi2 Adjustable Par30 is totally unique, providing unprecedented beam control with a smooth continuously variable beam angle from 15 degree spot to 60 degree flood. Powered by a single ultra-high CRI LED from Cree, the lighting quality is unmatched. Also, it’s dimmable. Many retail stores, hotels, offices, art galleries and museums depend on PAR30s for the majority of their lighting requirements.
The latest Lumicrest Pro Series – Apturi2 PAR30 is perfectly suited to lighting in galleries and museums, as well as high quality retailers, due their high color rendering index (CRI) of 98, strict colour variance control, and smooth dimming function. Never need to change lenses to adjust the beam angle. Now with a deft twist of the hand you can tune the beam angle any way you need to. Hanging a new exhibition in your gallery? Putting up a retail display? Optimal lighting control has never been simpler!

SIMPLY PERFECT COLOR
In the past century, a parade of energy-efficient lighting technologies have held out the promise of earth-friendly light. But in this rush to energy-efficiency, we’ve forgotten something very basic: color is as ancient and as important as light. Humans understand color – in the million years we’ve walked the earth, our eyes, our brains, and our bodies have learned what perfect, full-spectrum light means. Our behaviors, our emotional well-being, and our human interactions depend on seeing colors as we are meant to see them. When all the technological complexity is said and done, Soraa offers you simplicity. Simply Perfect Light. Energy efficient AND true in every color of the rainbow. VP₃ VIVID COLOR. NUANCES OF COLOR IN WHITE LIGHT
Many lighting technologies, including blue-based LEDs, have reduced quality of light to the starkness of color temperature. In that world, your choice of white light simply comes down to: warm white or cool? This ignores the importance of color rendering: do your colors appear as they would in natural, full-spectrum light? At the most basic level, color rendering of a light source is defined by CRI, which uses a defined set of 8 pastel colors and measures how true-to-natural they appear when illuminated by the source. Since most of us do not live in a pastel world, a practical and meaningful extension of CRI is to include deep colors, in particular a 9th color, red, whose rendering is defined by the metric R9. Soraa abandons this one-color-at-a-time approach in favor of a unified idea. A continuous spectrum, in which all colors – pastels, vivids, and everything in between - appear as they are meant to be. Soraa’s technology rests on the simple idea that natural visible light starts at violet at ends at red. Translating the idea to numbers, great color rendering requires light to have the right amount of spectral content in every wavelength from 400nm to 700nm.
We start with a GaN-on-GaN™ powered LED that emits violet light at a peak frequency between 410 and 420nm, not blue light like all other LEDs. We then use a three-phosphor mix, containing a blue, a green, and a red phosphor, which progressively reduce the frequency of the light so that it covers the entire range down to 700nm, or deep red. When we are done, we’ve created a full-visible-spectrum, continuous and unbroken from violet (400nm) to red (700nm). This technology is Violet-Emission 3-Phosphor, or VP₃, and the color rendering it creates is VP₃ VIVID COLOR. With this, we create our Soraa VIVID product series. CRI-95, R9-95, and much more. |
Violet light resides at the tail of the visible spectrum, and most of the time we do not think too much about it. After all, we were all taught that red, green, and blue makes white light. So we hardly noticed when blue-based LEDs killed violet.
But color scientists have long known that violet light plays an all-important role in our perception of another color – white. White in all its shades is ubiquitous in our environment. Whites convey the emotional meaning of clarity, brightness, and space. Manufacturers and marketers strive to create ever whiter whites. And the color of light that allows us to see true whites is violet. Soraa offers a solution that is radical in its simplicity. Simply Perfect Whites. VP₃ NATURAL WHITE. THE SCIENCE OF WHITESOur perception of whiteness is strongly influenced by the presence of fluorescent whitening agents in both natural objects (like teeth), and manufactured objects (like clothing and paints). These whitening agents are excited by the violet content in visible light, which our historical light sources – daylight, incandescents, and halogens - have contained. Thus, we live in a world with infinite shades of whiteness, determined by the level of fluorescence in each object.
Increasing adoption of blue-based LEDs now threatens this nuanced world. With their complete lack of violet content, peer-reviewed academic research shows that blue-based LEDs wash out the differences between whites. Bright or creamy, all whites look the same, yellowish and dull, and we lose the ability to tell one from the other. The same research shows that with Soraa’s violet-based LEDs, whiteness choices are as clear as the day. Soraa’s very efficient GaN on GaN™ LEDs have enabled us to make some unique choices. We have used the leeway this efficiency gives us, not only to provide more lumens per electrical watt, but also to tune our LED to emit light in the violet range of wavelengths, 400nm to 440nm. Unlike blue LEDs whose emission starts at 430nm, Soraa’s spectral emission begins at 400nm, providing all the fluorescent excitation needed to discriminate clearly between shades of white. However, unlike more traditional sources of light, Soraa’s products emit no harmful ultra-violet light. This technology is Violet-Emission 3-Phosphor, or VP₃, and the whiteness rendering it creates is VP₃ NATURAL WHITE. Bring back the whites in your world. |
