the drive plays an important role as the driving power device. Related to the LED driver problem, you can consult businesemen for details.
 

On the various parameters of the drive, there are output voltage, current, power factor, temperature and so on. The operating voltage of 1W LED lamp is about 3.2V. The working current is about 320MM. If the current is too large, it is easy to shorten its lifespan. If the driver is a low power factor, such as the 0.6 power factor,10W light will consume 16W. It is wastes. At the same time, for the low power factor, it will cause the heating of the drive increase and the heating will kill the electronic elements. In the purchasem you should know the repair rate at the same time. After all, now the damaged LED light is mainly for the drive. We can choose the better driver through these.
