How to exclude the driver is bad? Must read before buying!!!

Question: my home light started to be normal. After a period of time, it began to flash. Is it broken or is the drive broken?

Answer: began to use, with a period of time to flash, then the driver is broken, it is recommended to replace the driver.

Question: my home lamp used, opened for a long time not bright, waiting for about 15 seconds to light, what is the reason?

Answer: This is the drive, the internal components are broken.

Q: I bought the new driver according to the wattage of the lamp. Why is the lamp always flashing on the installation? Is the driver bad?

Answer: Flash there are several cases, the number of Watts drive than the lights flash, driving wattage less than the light may also be flashing. It is recommended to check whether the wattage of the lamp is falsely marked.

Q: too many driver models. I don't know what to do. How about that?

Answer: select drive according to the output (DC) voltage V number and current (ie: mA) to choose. It doesn't matter, but the gap can't be too big. The voltage and current are smaller than those of the lamp, which will not move, cause no light or no previous light, and may be flashing all the time. The voltage and current are too high to burn or flash.
