An essential part of the process of converting high-input electric current to low-output electric current is a low-voltage transformer. To power landscape lights, it reduces the voltage from 120 volts to typically 12 volts. A low-voltage transformer converts electrical current so that low-voltage fixtures, which comply with code requirements, can be put securely on or in the ground. https://texasgardenmaterials.com/landscape-design-houston-tx/landscape-lighting/
