[Note 2] The inverter open voltage should be larger than start up voltage, otherwise backlight

may blinking for a moment after turns on or not be turned on. And this voltage should
be applied to lamp for more than 1 second to start up, otherwise backlight may not be
turned on.

[Note 3] If driving current waveform is asymmetrical, mercury deviation inside of CFL will

incline to one side and consequently abnormal lighting may occur.
To prevent such unfavorable lighting, driving current waveform is asked to have
unbalance rate of less than 10% and wave-height rate of less than 2 +/- 10%.
And this driving waveform shall be confirmed in your system.
