Color Accuracy & Consistency

Spectral grade regulation

Color accuracy and consistency are derived from the spectrum. When observing the overlapped spectra from a batch of LEDs, the deviation is visually to find. The general LED will get a maximum 25% deviation which is the primary reason causing color shift and inconformity, but with Yujileds® spectral grade regulation, we achieve to 5% deviation.

Behind the spectral grade regulation is our elaborative control of the raw materials to reach up to 2.5nm tolerance binning, which determines the absolute accuracy and consistency.

Introduce 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 Yujileds® module, the performance can reach 1-2 step equivalent SDCM.

TrueChroma service, lifetime data tracing


We provides the Yujileds® TrueChroma service for a wide range of LED products, which is the tracing and analyzing support to every batch of LED production and saves for lifelong. The data can track the specific raw material information to that batch. This service is particularly important and desired for high-end requirements and high-value-added exact applications, and is also significant for long-term business development and cooperation, to solve the fear of attacks from behind.

Up to 0.0015 (CIE x,y) tolerance certification

We takes the lead to provide up to 0.0015 (CIE x,y) chromaticity tolerance (based on Yuji condition) as the specification when other LED manufacturers are still offering 0.006.


We all along consider the 0.006 tolerance meaningless except for liability exemption since it is getting close the 5-step SDCM with obvious visual color difference. The industrial LED production generates tolerance indeed but the nominal 0.006 is not helpful to resolve the evaluation of tolerance then the real chromaticity parameters.
