Do you use a 50Hz ballast for the lamp of 220v 60Hz
Three, if use the ballast in the lamps and lanterns is electronic inverter type (such as energy-saving fluorescent lamp and LED bulbs), applicable environment of power frequency is not limited to, as shown in the nameplate for not influenced by power frequency, can be free to use in 50 hz or 60 hz environment and there is no problem.
Second, if the lamps and lanterns is used within the ballast capacity limit flow (e.g., low cost design LED energy-saving lamps), suitable for the occasion of 60 hz, the capacitance will be smaller than apply to 50 hz occasions about 20%, so the current may be less than the rating of 20% of design, the brightness of the light may be reduced, but will not impact on the safety of lamps and lanterns;
It may not be possible, depending on the structure of the ballast itself. A, if the lamps and lanterns is used within the ballast is the inductive limit flow (e.g., low cost design of high pressure mercury lamp), suitable for the occasion of 60 hz, the inductance may be applicable to the 50 hz occasions about 20%, so the current rating of 20%, probably more than design flow effect and may make core magnetic saturation, led to the decrease of the inductance further... The resulting flow of light is damaged;
