FAQ:


What is the voltage of a white LED?




The typical forward voltage of a white LED is in the range of 3V to 5V. Since the best choice to power white LEDs is a constant current source and the input voltage range of a Li-Ion battery is below or equal to the LED forward voltage a new power supply solution is required.
