Common problem

1.Why does the lamp flash when connected to the driver?

There are two reasons: 

   First, the lamp has been damaged, the second is the lamp and the driver does not match

2.How to tell if the drive is good or bad?

Drive damage will not output voltage, you can drive the power in the case of the output of the

   positive and negative wire friction to see if there is a spark, there is a spark that the drive is good

3.How to distinguish whether the lamp is a full wattage?

      1. Look at the current output of the label on the drive

      2. Look at the shell heat sink,

      3. To see the lamp inside the gold wire is not a double gold wire
