Not all GU5.3 bulbs are 12 volts, though most are designed for low-voltage MR16 lighting systems. The term GU5.3 refers to the bi-pin base with pins spaced 5.3 millimeters apart, commonly used in track, recessed, and landscape fixtures. While most GU5.3 bulbs operate on 12V AC or DC, some newer LED models may support different voltages, so always check the manufacturer’s specifications to ensure proper compatibility with your transformer or fixture.
