To dim LEDs properly requires a PWM controller.  LED dimming is pretty
tied up in patents and patent litigation, so these aren't exactly in
over-supply.

But, if you have LEDs running off an unregulated supply with a proper
(as in magnetic, not electronic) transformer, such as an unregulated
wallwart PSU, and you plug it in across an incandescent load, it does
work.  Without a parallel incandescent load its not likely to work at
all well.
