How to choose a good LED lighting?

2.Strong anti-static LED, long life, and thus high prices. Generally more than 700V antistatic LED can be used for LED lighting. 

3.Consistent wavelength LED, the same color, such as the requirements of the same color, the price is high. Manufacturers without an LED spectrophotometer can hardly produce pure color products. 

4.Leakage current, LED is unidirectional conductive light, if there is a reverse current, then known as leakage, leakage current LED, short life expectancy, low prices. 

5.Light angle, use different LED light(LED bulbs for home) emitting point of view is not the same. Specific lighting angle higher prices. 

6.Life expectancy, the key to different quality is life, life is determined by the light fades. Light decline, long life, high prices. 

7.Chip, LED luminous body for the chip, different chips, the price is very different. Japan, the United States more expensive chips, the general Taiwan's chip prices lower than Japan, the United States, the lowest domestic. 

8.Colloids, general colloidal LED general epoxy resin, plus anti-UV and fire retardant LED(replacement LED bulbs for sale) prices more expensive, high-quality outdoor LED lighting should be resistant to UV and fire. 

From a health point of view, the use of non-toxic materials designed to higher prices of products, especially indoor LED lighting, do not be fooled by the choice of odor LED lighting. Now only a few LED manufacturers are using non-toxic materials to produce, you can directly smell the nose, smelly products much lower than the price of odorless, which contains excessive lead, mercury, cadmium and other toxins. From the perspective of applicable environmental safety, a reliable dust-proof moisture-proof design, materials, fire, UV, anti-low temperature cracking LED products, high prices.

As for the LED bulbs(Equivalent Incandescent bulbs LED bulbs supplier) are similar, take the most critical drive power, low-end products (including some big brands) using RC buck, RC buck work is: AC 220V input - CBB buck capacitor 400V 105J - full-bridge rectifier, the internal package 4 diodes connected in the form of bridge full-wave rectifier circuit and package - regulator, filter capacitor (parallel) - output, the internal use of two 474 and two 510. This method is more extensive, the peak voltage far exceeds the voltage regulator and capacitor voltage, it is easy to breakdown, may lead to electrical fires, giving users a huge risk. There are news reports that a consumer bought a cheap LED lamp exploded, the LED lights were bombed split, those who bought too cheap LED lights is equivalent to buying a time bomb at home, for the sake of life and property of the family the best lamp Take it down.
