1. The power failed. Some enterprises increase the rated power value of low-power energy-saving lamp , thus increase the price.
2. The initial effect of light failure. The index failed, the light efficiency of energy-saving lamps will reduce the service life shorter,can't get energy-saving, money-saving results.
3. Mechanical strength failed. The test is for : whether the head part will be loose or fall off, whether consumers will happen electric shock accidents when install or replace.
4. Power Factor failed. Some companies say a higher nominal value of the power in order to promote their products . The actual test can not be achieved.
5. Harmonic failed. As the electronic ballast input supply current harmonic content is too high, easy to pollution power and increase the loss of power to other electrical devices cause interference. Must strictly limit the current harmonic content to reduce the harm caused by harmonic pollution power.
6. Color feature failed.The color feature of energy saving lamp light is the reduction properties of objects, has a good color can make the object color in the light closer to daylight color, best embodies the characteristics of the original things. The failure of energy-saving lamp indicators, easy to eye fatigue and other damage caused to consumers.
