Introduction to 8mm White LED Voltage

The 8mm white LED voltage refers to the electrical potential difference required to operate an 8mm diameter white light-emitting diode (LED). These LEDs are widely used in various applications due to their small size, high brightness, and low power consumption. The voltage required to power these LEDs can vary depending on the specific model and technology used in their manufacturing.

Understanding LED Voltage

LEDs are semiconductor devices that emit light when an electric current passes through them. The voltage across an LED is directly related to its forward voltage, which is the voltage required to forward bias the diode and allow current to flow. In the case of 8mm white LEDs, the forward voltage typically ranges from 2.8V to 3.5V.
