1. Brightness LEDs have different brightness and prices. The LED used for LED lamps shall conform to the Class I standard of laser level.

2. The LED with strong anti-static ability has a long service life, so its price is high. Generally, the LED with antistatic voltage greater than 700V can be used for LED lighting.

3. LEDs with the same wavelength and wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.

4. Leakage current LED is a unidirectional conductive luminous body. If there is reverse current, it is called leakage current. LED with large leakage current has short life and low price.

5. The luminous angle is different for LEDs with different purposes. Special luminous angle, high price. Such as full diffusion angle, the price is higher.

6. The key to different quality of life is life, which is determined by light decay. Small light attenuation, long life, long life and high price.

7. The luminous body of chip LED is chip, and the price varies greatly with different chips. Chips from Japan and the United States are more expensive. Generally, chips from Taiwan and China are cheaper than those from Japan and the United States.

8. Chip Size The size of a chip is expressed in terms of its side length, and the quality of a large chip LED is better than that of a small chip LED. The price is proportional to the chip size.

9. The colloid of ordinary LED is generally epoxy resin. LED with anti ultraviolet and fire retardant is expensive. High quality outdoor LED lighting should be anti ultraviolet and fireproof.
