NettetLED replacement for low voltage halogen Low-voltage halogen lamps are operated with voltage of 12V. This voltage is generated by a transformer from the mains. If there are problems after switching to 12V LED lamps it could depend on the used transformer. NettetWith 12V systems, the lower voltage means more current must be supplied to compensate. For example, a 120V LED system will pull 1 Amp in a 120 Watt system, while a 12V LED system will need to pull 10 Amps to power the same 120 Watt system. Why does the amperage matter? fancy free midi
