High quality light
CRI is a measure of a light source's ability to show object colors "realistically" or "naturally" compared to a familiar reference source, either incandescent light or natural daylight. It is measured on a scale from 0 to 100. Natural daylight has a CRI of 100 and is what all light sources strive to replicate. CRI is merely an index value that considers 8 color samples. Though not included in the calculation of CRI, the CRI R9 special test color sample index is typically very low in normal LED lightings, reflecting the fact that they render red colors particularly poorly.
Luxuni offer LED lightings with CRI values above 95 and R9 above 90. This means the color accuracy and reproduction of our LED lightings are nearly perfect making them an excellent choice for retail, art galleries, museums, high end homes or anywhere extreme color accuracy is required.
Luxuni LED lighting use special LEDs with much less blue light than normal to ensure a safe light, which surpass the standard IEC/TR 62778.
Excellent color consistency
Luxuni LED lightings use special LEDs with much less blue light than normal to ensure a safe light, which surpass the standard IEC/TR 62778.
The distance from the target point in each ellipse is measured in SDCM (Standard Deviation of Colour Matching). An SDCM of 1 step means that there is no colour difference between LED chips, 2-3 SDCM means that there is hardly any visible colour difference. Colour consistency of 6-7 SDCM is accepted by the market and in line with the European EcoDesign – US Energy Star requirements.
As we all know, the best light is always the spots on the BBL (Black Body Locus), Luxuni LED lightings only use the LEDs in the bins most closely to the BBL with colour consistency < 3SDCM. Innovative internal design, optics and excellent heat dissipation ensure that color quality of our product is maintained throughout the rated lifetime which is more than 90% of their initial light output for more than 60,000 hours of operation (L90 > 60,000hours).
