How Many Volts Does A Small Led Use. In short, leds are like tiny lightbulbs. Usually voltage is pretty close to, but lower than, rectified line voltage in order to keep costs low. To calculate an led's power use, simply multiply the led's voltage (in volts) by the led's current (in amperes). This chart shows you that all visible light leds require at least 1.8v. However, leds require a lot less power to light up by comparison. They're also more energy efficient, so they don't tend to get hot like. The result, measured in watts, is the amount of power your leds. A red led will drop about 2.2v, so like you saw it can be powered from a 3v battery. This value is usually provided by the manufacturer That is why 9v led packages exist (3 diodes in series in one package). The amount of power needed, in volts, for the led to light properly. The typical forward voltage of leds are 1.8v (red), 2.0v. The voltage drop across a lit led is approximately constant over a wide range of operating current; Therefore, a small increase in applied voltage.
