Adding 'Oomph' to the Garden Solar Light : 7 Steps ...

Solar garden lights are intended to provide light for about four to six hours in full sun, less in less sun. As an alkaline battery is charged in a completely different circuit than one used for NiCd or NiMH batteries, what is more likely happening is that your garden lights are simply running off the battery without the solar cell being involved, other than to shut off the light in the daytime.

How to Build a Dark-activated Light Circuit

Dark-activated Light Circuit Schematic. The schematic of the dark-activated light circuit we will build is shown below: So, for this circuit, 3 volts is powering the circuit. This 3 volts is in parallel to a 100KΩ resistor and the photoresistor. In the middle of these 2 components is connected the base of the NPN 2N3904 transistor.
