Photography & Studio Lighting
Natural light is always the ideal light source for photographers. Nevertheless, it is not easy work to catch the sun in a day, and the suitable weather is always unpredictable. Also, considering the special effects and more efficient work for photographers, artificial lighting is necessary for supplementing or even replacing the natural light, however artificial light is a completely different concept compared to the sun, so selecting the right light is essential.
Color Rendition--the key to the right light.
High CRI - Color Rendering Index - Ra 95-98, R9 > 90
CRI is a measure of how accurately a light source illuminates objects' true colors. YUJILED 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.

TLCI - Television Lighting Consistency Index -TCLI > 95 (The metric for photographic especially.)
The TLCI metric was developed as an alternative to address the shortcomings of the commonly used CRI when used with photography equipment. Because the way cameras interpret light is slightly different to how humans perceive it, the TLCI attempts to provide a more accurate prediction of color fidelity of a light source for broadcast use.
There are LEDs with poor TLCI scores but high CRI results on the market. YUJILEDS officially introduces TLCI as the standard specification to help users distinguish and compare CRI and TLCI to more accurately evaluate the lighting quality for photographic lighting.

TM-30-18 Metric - avg Rf/Rg > 95 (A most comprehensive metric for color rendition.)
TM-30 metric is defined by Illuminating Engineering Society (IES), providing quantified measurements on overall average properties and describing a method for evaluating light source color rendition.
Compared to CRI, TM-30 picks 99 color evaluation samples from more than 100,000 collected world possible colors. Additionally, TM-30 separates the fidelity and gamut evaluations to present a most objective result.
YUJILEDS is the first one that introduce the latest TM-30-18 as a standard specification to help with LED users understand the actual performance with this metric. In a shoot scene that generates complex color environment, the performance with TM-30-18 contributes to a multidimensional evaluation for post production.

Color Accuracy & Consistency
CRI Uniformity & Consistency
Overall light uniformity is very important, and even has higher priority than single LEDs. This is because LEDs are usually mounted on strips or PCBs. Therefore, it is particularly important to maintain LED stability of performance and CRI value consistency in the process of mass production. The uniformity of LEDs is shown on the diagram from randomly samples.
YUJILEDS® SimpleBinning solution
We propose the innovative YUJILEDS® SimpleBinning solution when most LED manufacturers are providing complex binning systems. The optional bins are limited between 1-2 sections without compromising the color quality, which greatly simplifies the lighting design.
SimpleBinning provides statistically consistent color performance, with the YUJILED® module, the performance can reach 1-2 step equivalent SDCM.
Flicker Free
LED lights oftentimes exhibit invisible flicker - rapid fluctuations in brightness that occur many times per second. Because of its rapid speed, this "flicker" in an LED lamp may not be visible, but can have physiological and neurological effects on our bodies, such as eye strain, fatigue, headaches and difficulty in concentration.
YUJILEDS LED lights feature cutting-edge Yuji Zero-Glare Technology, designed to minimize glare and reduce eye strain during long creative sessions.

Lifespan > 54,000 hours
LM-80 is an industry standard that can help users evaluate lifespan of LED products. It refers to a method for measuring the lumen depreciation of solid-state lighting sources, such as LED packages, modules and arrays. Illuminating Engineering Society (IES) created a standard methodology that would allow customers to evaluate and compare the lumen maintenance of LED components.
Basically, the report is commonly used to evaluate the time of lumen depreciation from 100% to 70%, but data is measured lumen depreciation over 9000 hours and calculate how long it will take to 70%.
In Yuji’s report, the lifespan of LEDs under TM-21 standard L70 is >54,000 hours.
