Standard requires initial photosynthetic efficiency (flux) for 54 lm/w, or unqualified product sample measured values of the minimum of 1 # 33 lm/w, sample 2 # 34 lm/w. Unqualified will affect the quality of lamps and lanterns lighting, mislead consumers, especially children’s long-term use can affect vision; 3 it is to the individual input power and power factor of the products do not conform to the requirements of the standard.
Standard “the difference between the actual consumed power and the rated power for plus or minus 15% or less”, and of unqualified products measure value of 27% and 27%. The input power will reduce the service life, and at the same time also can affect safety circuit. Nominal value for the unqualified products power factor acuity 0.56-0.05 (0.51), and the measured values is 0.48, the express values have not reached. The power factor can not meet the standard demand may pollute the power grid, affect the quality of power supply; Four is the structure of the individual product index does not accord with a standard to ask.
If the connecting requirement of lamps and lanterns of lamps and lanterns has prescribed standards of connecting, this connection to lead an independent seat connected to the fixed wiring terminal or terminals, unqualified products without independent terminals after inspection. Do not use the terminal can make the lamps and lanterns in use external wiring and internal wiring connections are in danger of loosing off, cause leakage, electric shock accidents; Five is a sign of some products is not standard.
