How to choose LED light source

With the development of the market, as a consumer, choose LED is still to be calm, scientific analysis, choose the best cost-effective light source and lamps and lanterns, the following introduce the basic performance of several kinds of LED:

1、Brightness: LED brightness is different, the price is different. Used for LED lamps and lanterns should comply with the laser level Ⅰ class standard.

2、Antistatic ability: Strong antistatic ability LED, long life, so the price is high. Usually antistatic LED greater than 700v can be used in the LED lighting.

3、Wavelength: The same LED wavelength, the same color, such as request the same color, the price is high. If there is no LED light color separation instrument manufacturer, it is difficult to produce pure color products.

4、Leakage: Now LED is a one-way conductive lights, if there is a reverse current, called the leakage, if the LED’s leakage current is large, short life, low price.

5、Lighting Angle: Different LED light use have different lighting angle. Special lighting angle, the price is higher. Such as the diffuse angle, the price is higher.

6、Different LED quality is the key to life, life is decided by LED lumen maintenance. Low lumen maintenance, long service life, long life, high price.

7、Chip: LED’s illuminant is chip, different chip, there is large differences in price. Chip in Japan and the United States  is more expensive, generally chips price in Taiwan and domestic is lower than the United States and Japan.

8、Colloid: ordinary LED colloid generally for epoxy resin, LED uv radiation and fire retardant added are more expensive, high quality outdoor LED lighting should be uv and fire prevention.

Because of the LED is a new product, the china national standard lag, but countries to provide product qualification testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification, LED lamp price is higher, because these products on the safety design are reliable. Lisun Group award CE certificate and we are CIE Supportive Member, all of the LED test reports are accurate.
