I have a small 4W "night light" in my bathroom that is controlled by a photocell such that it only comes on at night. This light definately exhibits a stroboscopic effect. I suspect that the electronics in the photocell-control include half-wave rectifiers that result a more pronounced flicker.
That said, none of the other incandescent bulbs in my house exhibit flicker.
