Another Reverse engineered circuit diagram of a mass produced solar LED light. This light also automatically turns on when there is no light falling upon the solar cell but this circuit waits untill it gets bit darker outside than the one above. Although battery charging is through a schottky diode, some charging efficiency is lost in the 330 ohm resistor during daylight time.
