I have a host of LED Xmas lights up this year. Broadly falling into 2 types.
1. Power and controller (flash rate/pattern etc) in 1 unit - you'd need a DC-AC inverter to run these
2. Power adapter with the controller separated on the cable - look at the power adapter it should have a DC voltage and current (amps) spec on it.

Some of mine are rated at 24VDC at 150mA so I could run them off a 24VCD supply and not the adapter quite easily
