Hello,
Is the attached mains waveform ever likely to occur? (i mean in the mains system and not due to any triac etc at the customer premises)
As you can see, it keeps going to zero for an interval, then suddenly coming back on at the mains peak.
As you can well imagine, this kind of waveform would be very bad for Single stage Power factor corrected LED lights, because they have little capacitance at their input, and this type of waveform could cause overvoltage ringing with the input LC filter of the LED light.
