All the LED lamps that are available locally have noticeable flicker, and I have the same problem with the lamps that I've ordered online. Is there any device that could phase-shift 220 V 50 Hz AC home electricity so that I could run two LED bulbs out of phase from each other?
I have read that stadium lighting uses three 120-degree phases to handle flicker. I would thus prefer such a system for my LED lamps, but if a device with two 180-degrees phasing exists I would be happy with that as well.
