Yes but I guess the amplitude of the flicker must be very low? I'd have thought that if it was at all significant it would be very visually obvious at 50-60Hz

  It's really more like 120Hz since the polarity doesn't matter for incandescents.

    But you can stabilize the current quite nicely if you know how. This is almost never done on cheap LEDs. Except IKEA's leds, they were surpricingly good in some test lately.
