How to choose good LED string light

Edit:Lighteer Technology LimitedUpDate:Nov 12, 2018

1, LED brightness is different, the price is different. LEDs for LED luminaires should be suitable for Class I specifications such as lasers.


2, anti-static ability of the LED, long life, so the price is high. Generally, LEDs with an antistatic level greater than 700V are used for LED lighting.

                

3, the wavelength of the common LED, the color is common, if the required color is common, the price is high. It is difficult for producers without LED spectrophotometers to produce pure color products.


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


5, the illuminating point of view, the use of different LEDs, the illuminating point of view is not the same. The specific illuminating point of view price is higher.


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


7, the wafer, the LED illuminator is a wafer, different wafers, the price difference is very large. The chips in Japan and the United States are relatively expensive. Generally, the price of wafers in Taiwan is lower than that in Japan and the United States, and the lowest in China.


8, colloid, general LED colloid is generally epoxy resin, LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to UV and fire.
