With the rush into the market, as consumers, the selection should still be calm, scientific analysis, and the best cost-effective light sources and lamps, the following basic performance:

1. The brightness is different, the price is different. For lamps and lanterns should meet the laser class I standard.

2, antistatic ability, strong antistatic ability, long life, so high price. Usually anti-static is greater than 700V can be used for lighting.

3. The wavelength is the same, and the color is the same. If the color is required to be the same, the price is high. It is difficult for a manufacturer without a spectrophotometer to produce products with pure colors.

4. The leakage current is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage. The leakage current is large, life is short, and the price is low.

5. The lighting angle is different for different purposes. The special lighting angle, the price is higher. Such as the full diffusion angle, the price is higher.

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

7. The luminous body of the wafer is a wafer. The price of different wafers varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States.

8. Wafer size The size of a wafer is expressed by the side length. The quality of a large wafer is better than a small one. The price is directly proportional to the chip size.
