There is a wirewound transformer inside for galvanic isolation.
The internals vary, most don't
have this symbol it means it isolates and also has overload protection, without the latter the isolation could be compromised.
This one has the SELV mark, which means separated extra low voltage so should have a transformer inside, it also shows 0 - 105 VA so no problem with under load, no where does it give the output frequency, neither does it publish a maximum cable length, it is very likely one of these would run LED lights without a problem. However the LED lamps I bought from Lidi were clearly marked 50/60 Hz so one is taking a chance.
I think it is unlikely adding a diode which a LED lamp clearly is will turn the power supply into a radio transmitter of any problem strength. However I have know where a rusty bolt caused radio interference where rust was acting as a diode. The problem with the suck and see approach is you may not know what it knocks out, could be stopping your fire alarms working, who knows? When we test we do not test all possible effects, we hope that has already been done by manufacturer, personally easy way is move to 230 volt.
English differs from many other languages in that words can change their meaning, decimate comes from Latin and was when the Roman legions lost a battle they would kill one in ten to make them fight harder next time, deci = ten so is a precise number, however today this word seems to have reversed its meaning and is considered by many to get rid of nearly everything. And if you look it up in a 1950 dictionary it will say get rid of one in ten, but in a current dictionary it will say get rid of nearly everything possibility with a foot note to old meaning.
We are lucky with transformer, most call the switch mode power supply an electronic transformer so giving them two different names, the "driver" however was always used to refer to a current regulated device, however today it is also used to describe a voltage regulated device used to supply the real driver.
So all we need to do is remember a transformer and electronic transformer are not the same, is that so hard? As English goes what is wrong is not calling the wire wound version an "induction transformer" in some cases we do call it a tordonal transformer and really for lighting there are very few with the traditional iron core, so it is the people who call them transformers with no type stated who should be criticised, not those using the name electronic Transformer however this has already been done to death so why bring it up yet again?
