Unfortunately the lighting industry does not seem to be able to stick to the same name for devices, but be it a driver, switch mode power supply, pulse width modulated supply, transformer, or electronic transformer basic point is some thing goes between the LED and the AC mains, be it a box of tricks or built into the bulb, there is always some thing to do both or either of two things, limit the current and limit the voltage.
Some where there should be a label, it may say 220-240 volt AC 3 watt, or 12 volt DC 3 watt, but some where it has to have it written on it what it is.
The International Electrotechnical Commission (IEC) has called the plug show C7 but there is no fixed voltage, I have seen them used with 120 volt AC 60 Hz and 230 volt AC 50 Hz, so you simply can't look at pictures and give answers.
One actually have to read or measure, some times we have a good idea, as in the UK nearly all homes have a 230 volt supply at 50 Hz, I have seen homes in the UK with 110 volt DC supply, and 120 volt AC supply, but rather rare.
Likely the C7 connector can be connected to the choc block shown, but only you can work that out for sure.
