High CRI LED Lighting
By YUJILEDS.
Not all white light is the same. Many of the incandescent and halogen "replacement" LED lights currently on the market use less energy but are not true replacements as the white light they emit is of relatively poor quality. In applications where appearance is of paramount importance, light quality cannot be compromised.
VTC high color rendering index LED lights dramatically improve the appearance of products by allowing colors to appear clear, vivid and distinguishable all while consuming significantly less energy. By taking a slightly different approach and creating an innovative emission spectrum, our LED lights have achieved the highest color rendering available using the most advanced technologies, offering a true energy efficient replacement.
CRI (color rendering index) is a measure of how accurately a light source illuminates objects' true colors. Our LED lights have CRI values of up to 98, indicating that our LED lights are able to produce white light that approximates halogen or incandescent lighting and natural daylight.

Uneven, high emission peaks are visible across the spectrum.
Various colors are missing from the spectrum.
The red part of the spectrum is deficient in standard LEDs.
Cyans are also missing.
The entire visible spectrum is represented evenly and naturally in our 98 CRI LEDs.
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 blue-chip LED lights, reflecting the fact that they render red colors particularly poorly. Yuji LED lights have Ra values all above 90, and show superior testing results for the recently developed CQS (Color Quality Scale) as well.
Due to our innovative method of producing white light through a different type of chip and multiple phosphor conversion, we have achieved white LED light that is both quantitatively and qualitatively superior.

YUJILEDS at 2700K follow the spectral curve of an incandescent lamp very closely. Unlike competing incandescent "replacements" on the market, YUJILEDS provide full spectrum coverage at both ends of the spectrum.
YUJILEDS at 6500K provide spectrum coverage that is unmatched in quality and breadth. Competing LEDs have a significant "blue spike" to produce a cool color temperature point, which can be very problematic for rendering daylight color points.
What happens when we implement a hybrid solution mixing a high CRI warm-white color temperature LED with a high CRI daylight-white color temperature LED? Our test results show that at all color temperatures in between (2700K - 5600K), high CRI is maintained, including R9.
High CRI full spectrum lighting can dramatically improve the appearance of objects, particularly in retail stores, shops, super-markets, museums, galleries and exhibits where red colors are prominent and presentation and appearance are critical. High CRI LED Lighting also has other applications in areas such as hospitals or textile industries where color differentiation is crucial in work performance. High CRI LEDs are ideal in locations where savings in energy consumption are desired, yet quality of light must be maintained.
Color rendering is crucial for displaying any type of exhibition, particularly those with vibrant reds.
Appearance is critical for food and produce. High CRI LEDs can make food look fresh and appetizing.
Precise and accurate distinctions of color are needed in visual arts and photography.
Looks are everything in retail. Why let low quality light diminish your products' appearance?
Subtle gradients and color differences in fabrics can only be seen under good quality lighting.
A patient's flushed, red face might go undetected under low quality light.
Our high CRI LED technologies utilize two different methods of re-creating natural lighting. See below for a quick overview of the differences.
| CRI (min): | 95 | 95 |
| CRI (typical): | 97 | 98 |
| R9 (min): | 90 | 90 |
| R12 (min): | 60~80 | 90 |
| Luminous efficacy: | 80-140 lm/W | 65-85 lm/W |
| Form factors: | 2835 & 5730 SMDs, 10W, 25W & 100W COBs | 2835 & 5730 SMDs |
BC series high CRI LEDs using blue die are well suited for applications requiring high power, efficiency and excellent color rendering. YUJILEDS phosphor expertise provides a no-compomise, high CRI / high efficacy solution.
VTC series ultra high CRI LEDs using violet die provide the highest rendering quality in the industry - up to 98 CRI. Output covers the entire spectrum including violets, cyans, deep reds, and brings out colors perfectly. Ideal for applications where high color quality is of absolute importance.
