1. The lamp power is unqualified.
Some companies increase the nominal power value (ie, the rated power value) of low-power energy-saving lamps to increase the price.
2. The initial light effect is unqualified.
If the indicator fails, the light efficiency of the energy-saving lamp will be reduced, and the service life will be shortened, which will not achieve the effect of energy saving and money saving.
3. The mechanical strength is unqualified.
This test is for whether the lamp cap part will loose or fall off, and whether it will cause accidental electric shock accidents during installation or replacement.
4. The power factor is unqualified.
Some companies have set the power factor nominal value to be high for the purpose of promoting the product.
5. The harmonics are unqualified.
Because the harmonic content of the power supply current at the input end of the electronic ballast is too high, it is easy to pollute the power supply, increase the loss of the power grid, and cause interference to other electrical equipment. Therefore, the harmonic content of the current must be strictly limited to reduce the harm caused by the harmonic pollution power supply.
6, the color characteristics are not qualified.
The color characteristic of the energy-saving lamp refers to the reduction characteristics of the light to the object, has good color rendering, can make the color of the object closer to the color under the light under the light, and can best reflect the original characteristics of the object. The higher the color rendering, the more the color Presenting things as they are. Energy-saving lamps that fail this indicator are likely to cause eye strain and other injuries to consumers.
