We have Compact Fluorescent lamps hooked up to a dimmer circuit, and they are striating (flashing) at exactly the same frequency, even at full power setting, which tends to tell me it's circuit related. Now I know that a dimmer circuit uses a triac to chop up the waveform, and therefore we're witnessing some by-product of this. However, the striations seem to be a lot slower than 60Hz, otherwise I'm not sure we'd be able to see them. Anyone know the physics of striations of Fluorescent lamps? If and where the problem is in the circuit, ballast, or lamps? or how to fix this? Thanks ahead of time.
