6) use any of the above methods but with UV leds and coat the glass on your bulb with phosphor, giving some extra buffer to the flicker by way of a slow brightness decay. I'm fairly sure the IKEA bulbs use the above method. If you turn them off they have an afterglow for a couple seconds.

I always assumed that was the capacitor draining.

  Could be, but then there's also the CRI rating on these ikea bulbs being rather good at around 95.6 which hints at phosphor as well. I could be entirely wrong though, someone should probably dismantle one and figure it out.
