As a matter of interest, why to the 12 Volt ones seem to be more
problematic than the mains ones?


Current to be supplied?

10W from 220V, current to be supplied 0.045 Amps

10W from 12V, current to be supplied 0.833 Amps

The low supply voltage power supply is switching high currents.
The mains supply is switching low currents.
