How To Choose LED Light Bulb
Jun 15, 2018

1, LED output luminous flux (LM number) is different, the price is different. LEDs used in LED lamps should conform to the standard of Ⅰ for laser grade.

2, anti-static capacity of strong anti-static led, long life, thus high prices. Usually a single anti-static more than 700V of LED can be used for LED lighting.

3, wavelength consistency of good led, color consistency, such as the requirements of color consistency, the price is high.

It is difficult for producers without led spectrophotometer to produce pure color products.

4, leakage current

LED is a one-way conductive light-emitting body, if there is a reverse current, called leakage, leakage current large LED, short life, low price.

5, the luminous angle uses the different led its luminous angle is dissimilar. The special luminous angle, the price is high. such as full diffuse angle, the price is higher. 

6, life is different, the key to quality is life. Life expectancy is determined by light decay.Light decay small, long life, high price.

7, Wafer LED light-emitting body for the chip, different chips, the price difference is very large.Japan, the United States, the chip is more expensive, the general Taiwan and domestic chip prices are lower than Japan, the United States (CREE).

8, the size of the wafer chip size to edges, large chip led quality is better than small chip. The price is proportional to the size of the wafer.
