[RE-wrenches] Light Flicker Off grid

[Maverick Brown]

May I suggest getting a couple high quality LED bulbs. CREE and other brands have a high Power Factor. The intermittent power factor swings of the washer may be jacking with the PF of the cheap bulbs. 

Thank you,

Maverick

We can see a corresponding distortion of the wave form on an oscilloscope, but RMS voltage is steady at 117 vac.  It does not cause trouble with incandescent lighting, and the washer works fine.
