YUJI full-spectrum SunWaveTM lighting technology closely replicates 99% of the sunlight visual spectrum, filling the spectrum gaps that conventional LEDs miss, with a smoother distribution and no sharp blue peaks. This effectively reduces blue light exposure, helping to alleviate visual fatigue. Unlike traditional lighting, YUJI lighting provides a more natural indoor lighting environment that enhances human well-being. Our technology goes beyond just a single spectrum—our fixtures feature dynamic color temperature adjustment, mimicking the natural transition from day to night to optimize visual comfort.
We design our advanced lighting solutions to bring lighting closer to nature, addressing both visual and physiological needs in every aspect, promoting a healthier and more comfortable environment indoors.
YUJI SunWave™ lighting fixtures bring the natural circadian rhythm into both work and living spaces, enhancing well-being on a biological level. Our fixtures do more than just simulate the visual spectrum of the sun; they are specifically designed to align with the biological rhythm. Key parameter m-DER are crucial for evaluating circadian rhythm performance and are precisely matched to natural light across various color temperatures.
This creates an indoor lighting environment that closely mirrors nature, promoting a comfortable, healthy, and productive atmosphere. The result is lighting that supports both physical and mental well-being throughout the day.
YUJI is a leader in high CRI lighting fixtures, SunWaveTM technology achieving an exceptional CRI of 98 and a TM-30 index (Rf 98, Rg 100) across various color temperatures, far surpassing the CRI 80 commonly used in the market. (Sunlight has 100 score of CRI and TM-30 score). A higher CRI indicates that the lighting more accurately represents the true colors of objects, thanks to its full-spectrum lighting that includes a broader range of wavelengths to reflect more colors. This makes YUJI lighting ideal for environments where color accuracy is crucial.
In addition to the general CRI rating, special CRI indices like R9 (deep red) and R12 (saturated blue) are critical for evaluating color accuracy in specific hues. Our fixtures have achieved R9 and R12 values of no less than 95, setting a new standard for high-quality visible light performance. With this, YUJI has elevated lighting quality to an unprecedented level, providing a lighting experience that closely mimics natural sunlight.
