What happens when you put a LED bulb in a dimmer fixture

[nigelf2010uk]

Is the flickering caused by the bulb or by the dimmer switch - most dimmers get their power through the bulb and need a minimum wattage (usually around 30w) being pulled by the bulb to work correctly, a normal 20w bulb will also flicker like that when used with most dimmers. A more interesting test would be to fit an LED bulb into a 2 or 3 bulb ceiling rose keeping one regular bulb fitted (either filament type or halogen) to make sure the dimmer has enough power and see if the LED will then dim.

well use a proper DC dimmer, AC dimmers dont work on DC LEDS

Not Even LED lights rectified to AC.. It has to be on a DC circuit with a DC Dimmer switch :-\
