Did you know that the LED can be used as a light detector?In fact green LEDs are the best for this, but all LEDs will detect light and produce a voltage equal to the characteristic voltage-drop. The current they produce is very small, only the super and high bright one can produce a higher output due to the fact that their crystal is more efficient at converting light into electricity.
