220V LED light's?? "oops"

I found some cool little LED lights on Ebay, but I did not notice that they are powered by 220V. I am not sure how to wire them or if I can even use them.

Can I use a Power Converter Adapter AC 110V to 220V step up & down volt transformer to power these lights?

My second question is about the transformer that comes with the lights. It has 2 red wires that supply 220V input to the transformer and 1 black and 1 red wire that supply 250mA/DC2.5V-12V to the LED light. Can I use a 110V to 12V transformer to power these lights? Are the 2 red input wires both hot wires?

My third question is what size wire should I use? I used 12/2 with ground...will that work or should I get some smaller/different wire?

Here are the light's features:

Modle: 3W ceiling downlight
Input Voltage: AC 220V
LED Type: SMD5730
Power: 3W
Colour: Warm White(2800- 3000K); Pure White (5500-6000K)
Dimmable: Yes
Size: 8.7cm x 8.7cm x 2.2cm - 3.42inch x 3.42inch x 0.86inch

The eBay link would be helpful but it sounds like all you need to do is to get a 120vac--->12v? supply.

Is that a direct quote ?

The two red wires to connect to the 220 volt source can be connected to either a hot-neutral line (non-USA) or to two hots (US, Canada, others). Although equipment should accept +-10% voltage tolerance, there is a chance that 240 volts in the US may burn out the 220 volt lights.

The power supply has other components, namely diodes, in addition to the transformer to rectify the 12 volt transformer raw alternating current output to 12 volts direct current.

If you substitute a power supply of your choosing, namely 120 volts input to 12 volts output, you have to get DC output to match what the lights need.

Actually, try the light with the original power supply first as-is on 120 volts.

The lights say they accept 2-1/2 volts to 12 volts. If the existing power supply delivers at least 5 volts with 220 volts input then it will deliver at least 2-1/2 volts with 120 volts input and the lights will still work.
