1. LED beads have different brightness and prices. The LED used for LED lighting fixtures should comply with the Class I standard for laser rating.
2. LED with strong anti-static ability has a long lifespan and is therefore expensive. Usually, LEDs with an anti-static voltage greater than 700V can be used for LED lighting.
3. LEDs with consistent wavelengths and wavelengths have consistent colors. If color consistency is required, the price is high. Manufacturers without LED color separators find it difficult to produce products with pure colors.
4. Leakage current LED is a unidirectional conductive luminous body. If there is reverse current, it is called leakage. LED with high leakage current has short lifespan and low price.
5. LEDs with different lighting angles and purposes have different lighting angles. Special luminous angle, high price. If it has a full diffuse angle, the price is higher.
6. The key to different qualities of lifespan is lifespan, which is determined by light decay. Low light attenuation, long lifespan, long lifespan, and high price.
7. The luminescent body of chip LED is a chip, and different chips have significant price differences. Chips from Japan and the United States are more expensive, while chips from Taiwan and China are generally priced lower than those from Japan and the United States. LED beads are generally selected from imported sources.
