However, blue and white LEDs can begin conducting from 2.5-4V. So many projects and products have LEDs in them and it’s important to know the voltage and current required when using them. Check out the V F … The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can cause a large change in current. Current through the LED must be regulated by an external circuit such as a constant current source to prevent damage. Since most common power supplies are (nearly) constant-voltage sources, LED fixtures must include a power converter, or at least a current-limiting resistor.
