Purchase of LED lights

lights PURCHASE

1. The LED brightness (MCD) is different and the price is different. The LEDs used for LED lamps should meet the laser class I standard.
2. LEDs with strong antistatic ability have long life and high price. Usually LEDs with anti-static greater than 700V can be used for LED lighting.
3. LEDs with the same wavelength have the same color. If the color is required to be the same, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.
4. Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have short life and low price.
5. LEDs with different lighting angles have different lighting angles. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher.
6. Lifespan The key to different qualities is lifespan, which is determined by light decay. Low light decay, long life, long life and high price.
7. The luminous body of the chip LED is a chip, and the price of different chips 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 (CREE).
