I've tried to hoard 5-10 years worth of incandescent ceiling fan bulbs. The LED ones tend to flicker unless the A/C is absolutely perfect.
In a properly designed driver board AC current issues should never be a problem because the AC is rectified to DC by the board since LEDs run on DC. If their is a dimmer in the circuit (usually true for ceiling fans) the driver senses the reduction in voltage and strobes the LED using pulse width modulation (you can't technically dim them, they are either on or off). So either you are one of the people that are more sensitive to strobing or the bulbs have poorly designed driver boards.
