Reverse engineered circuit diagram of yet another commercially produced solar garden lamp. This one depends upon a CDS photocell to turn the light on at night, and although more complex than the circuits, it allows the battery to charge more efficiently.

Reverse engineered circuit diagram of one more commercially produced solar lamp. This one is very similar to the one above, but it is brighter and contains an extra capacitor.

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 [...]
