Industry-Standard 2856K Illumination with Unmatched Fidelity

YUJILEDS NormLite™ series delivers the most precise replication of CIE Standard Illuminant A (2856K) available in LED technology. Certified compliant with CIE 15:2018, ISO3668:2017, AATCC EP9:2021, and ASTM D1729-96 standards, our bulbs set the benchmark for color-critical lighting applications.

YUJILEDS utilize short-wave excitation and multiple phosphor technologies to create a light source spectrum that compensates for the energy loss typically seen in conventional LEDs, particularly in the red light spectrum. This approach also reduces the intensity of blue light in the short wave, making the LED light source more closely resemble the luminous quality of traditional tungsten filament lamps.

Origin of Illuminant A

Illuminant A is one of the standard light sources defined by the International Commission on Illumination (CIE). It represents the spectral distribution of an incandescent tungsten lamp with a correlated color temperature (CCT) of approximately 2856K. Its spectral energy is concentrated mainly in the infrared and red visible regions, with minimal blue light emission, closely resembling traditional tungsten filament lighting.

Advantages of CIE Illuminant A

  • High Color Rendering: Its continuous spectrum across visible wavelengths ensures accurate color reproduction, making it ideal for photography, art exhibitions, and color-critical applications.
  • Low Blue Light Hazard: Due to its minimal blue light component, it is gentler on the eyes, suitable for prolonged use in museums, laboratories, and sensitive environments.
  • Stability & Consistency: As a CIE standard, it provides a reliable spectral reference for optical experiments and color calibration.

  • Five Metrics of Circadian Rhythm Lighting

    Five Metrics of Circadian Rhythm Lighting

    Circadian rhythm lighting is no longer a novel concept that everyone may has different understandings of it and it could be from simple color temperature tuning to comprehensive spectral power distribution, or from simple brightness diming to follow the ipRGCs (intrinsically photosensitive retinal ganglion cells) rhythm feature to design the dimming program…here we will introduce five key metrics that the circadian rhythm lighting will never get around of these and they stand for the non-visual biological effect from light, and understanding these metrics are particularly important for designing the new era of human-centric lighting.
