If the 12V power supply, you need to match the 12V power supply, general AC DC can be, but must not directly connect to 220V power.
There are two kinds of LED spotlights, the 12V supply voltage and the 220V supply voltageIf the 220V supply voltage, without additional transformers, the lights have been built with transformers.
LED lamp with DC, and we are the city electricity 220V AC power supply, it is certainly a transformer, but generally LED lighting products which are built-in driving power, you can not be seen from the outside, as long as access to electricity, do not need to add transformer.
