First, the lamp power fails
Some companies increase the nominal power value (ie, rated power value) of low-power energy-saving lamps, thereby increasing the selling price.
Second, the initial light efficiency failed
The failure of this indicator will reduce the light efficiency of the energy-saving lamp, shorten its service life, and fail to achieve energy-saving and cost-saving effects.
Third, the mechanical strength failed
This test is for whether the lamp head part will be loose or fall off, and whether it will cause accidental electric shock accidents during installation or replacement.
Fourth, the power factor failed
In order to achieve the goal of promoting products, some enterprises have markedly high power factor rating. The actual test cannot be achieved.
Fifth, harmonics failed
Because the harmonic content of the supply current at the input end of the electronic ballast is too high, it easily pollutes the power supply, increases the loss of the power grid, and causes interference to other electrical equipment. Therefore, the harmonic content of the current must be strictly limited in order to reduce the harm caused by harmonic pollution power.
