Voltage impact test -CHZ lighting manufacturers From China, The LED lamps produced by CHZ will have a high and low voltage impact test. See if the lamp can withstand the impact of high voltage 300V, medium voltage 220V and low voltage 100V; first high voltage impact for 10 minutes, then medium voltage impact for 10 minutes, and then low voltage impact for 10 minutes. The higher the frequency of impact, the higher the drive requirements. It is required that the lamps and lanterns shall not have any electrical abnormalities such as electric leakage or non-lighting after the impact test.For countries and regions with large voltage fluctuations, this test is very necessary.
