Capacitors burning through in PSU (AC-DC) of 3W LED
It is not a case of overpower. Most probably you have a not so stable AC grid in Patagonia and the drivers are being destroyed by Surge or Burst events on the AC side. Normally in the no-name drivers the protection against such events is not really effective since some money can be saved when not implementing. Question: Is there any construction work, with drill machines for example, around? Is there a motor connected on the same circuit? Such loads are well know to cause surges on the mains damaging sensitive devices.
