Now buy LED Flood Light Series, who are afraid of buy defective lamp, poor quality, lack of earthen lamp, or consumes large LED lamp, low power factor transformation base lamp, such injury money, and also sad. With the rapid development of LED lighting industry, LED drive power supply manufacturer and swell. Many entrepreneurial firms and also set up our own factory. LED drive power supply technology is not yet mature, not issued relevant specification, industry. A mess In such cases, the development of many manufacturer of lamps and lanterns is not don't want to buy a good LED power supply, but do not know how to discern the stand or fall of LED power supply, but also worried that took a high price to buy the poor quality of the LED power supply.
So the quality of LED power supply, how to judge? What the influence factors of it? Now teach you a few quick and easy way to identify the quality of LED power supply.
A, PFC (power factor)
But not necessarily high PFC is good, but also the whole of oblique wave is small, small ripple, low interference (because some manufacturers deliberately do PFC is high but ignore this part electromagnetic compatibility).

Second, the conversion efficiency
Conversion efficiency of high and low, the size of the deviation and stability, for example: AC170-250 - v voltage range, this work I can try to debug, from 170 v to 250 v voltage changing from low to high, can see on the power meter "conversion efficiency, PFC" volatility is big, to prove its stability.
Third, whether the rise of temperature of the power supply is high.
Such as the power supply itself the higher the temperature, the greater the damage of components.
