1. Luminous flux binning: luminous flux value is an indicator that LED users are very concerned about, LED application customers must know which range of LED luminous flux they use, so as to ensure the uniformity and consistency of their product brightness.
2. Reverse leakage current test: reverse leakage current is lower than the required value under a certain voltage, and the reverse leakage current of LED is too high due to static electricity, chip quality and other factors in the production process, which will bury great hidden dangers for LED application products, and it is easy to cause LED dead lights after a period of use.
3. Forward voltage test: the range of forward voltage needs to be within the permitted range of circuit design, many customer design drive light-emitting tube lighting is powered by voltage, the forward voltage size will directly affect the change of the overall parameters of the circuit, which will bring hidden dangers to product quality. In addition, for some products with circuit power consumption requirements, it is desirable to ensure that the forward voltage is as low as possible under the same luminous efficiency.
4. Relative color temperature binning: For white LED color temperature is a parameter used more in the color industry, this parameter can directly show whether the LED tone is warm or cold or white.

5. Color coordinate x, y binning: For white light or monochromatic light, you can use color parameters to express which color area the LED is in, and generally require four points x, y to determine a color area. It must be ensured by certain test means whether the LED falls in the required four-point x, y color area.
6. Main wavelength binning: For monochromatic light LED, the main wavelength is an important indicator to measure its color parameters, and the main wavelength directly reflects the visual perception of the light of the LED by the human eye.
7. Color rendering index binning: the color rendering index is directly off to the degree of color change of the light on the object, which is very important for LED lighting products.
