what is the right Forward Voltage of LEDs?

Recommended Posts

Different kinds of LEDs have different forward voltage requirements. Non-bright LEDs tend to require less voltage than bright LEDs, since bright LEDs need more power to work. Typical VLED values are 1.7V for non-high-brightness red, 1.9V for high-brightness high-efficiency low-current red, 2V for orange and yellow, 2.1V for green, and 3.4 to 3.6V for bright white and most blue types.
