The first,power failure. Some enterprises a low-power energy-saving lamp nominal power value (ie rated power value) is raised to increase the price.
Second, the initial light effect failed. The index failed, the light efficiency of energy-saving lamps will reduce the service life shorter reach energy-saving, money-saving results.
Third, the mechanical strength failed. The test is whether it will produce for the head part of the loose or fall off, whether consumers will install or replace electric shock accidents.
Fourth, the power factor failed. Some promotional products companies in order to achieve the purpose of the nominal value of the power factor standard was high. The actual test can not be achieved.
Fifth harmonic failed. As the electronic ballast input current harmonics of high power, 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.
Sixth, the color characteristics of failure. Energy saving lamp light color feature is the reduction properties of objects, with good color rendering, color can make objects in the light closer to daylight color, best embodies the characteristics of the original things, the more significant the higher color Show true colors of things. The failure of energy-saving lamp indicators, easy to eye fatigue and other damage caused to consumers.
