How to choose a good LED light bulb

1. (LED light bulb)LED output luminous flux (LM number) is different, and the price is different. The LED used for LED lamps shall comply with class I standard of laser grade.

2. (LED light bulb)The LED with strong antistatic ability has long service life and high price. Generally, the LED with monomer antistatic greater than 700V can be used for LED lighting.

3. The LED with good wavelength consistency has 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 of the LED light bulb
(LED light bulb)LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. Led with large leakage current has short service life and low price.

5. (LED light bulb)The luminous angle of LEDs with different uses is different. Special luminous angle, high price. Such as full diffusion angle, the price is higher.

6. Life is different, the key to quality is life. The lifetime is determined by light decay. Small light attenuation, long service life and high price.
