modification of a typical solar path light circuit

modification of a typical solar path light with a standard 1000ma hour nimh aaa cell. i then replaced the small 4 cell solar panel with a larger 4 cell unit, which produced 150ma in the sun. next, i simply changed the 470uh coil on the circuit board to a 22uh coil. the lower inductance increased the battery current to 40ma when the led light was on, which translated to about 13ma led current.
