1. A solar-controlled light device comprising:
- (a) a solar cell having a positive end and a negative end wherein said negative end is connected to a common ground;
(b) power storage means for storing electrical energy received from said solar cell and for releasing said electrical energy, said power storage means having a positive end and a negative end wherein said positive end is connected to said positive end of said solar cell and said negative end is connected to said common ground;
(c) light source for receiving said electrical energy, said light source having a positive end and a negative end wherein said negative end is connected to said common ground;
(d) circuit-control means for controlling a circuit from said power storage means to said light source by selectively opening the circuit thereby placing the device into an open mode to power said light source and for closing said circuit and placing the device into a closed mode and terminating said circuit and power to said light source; and
(e) current-control means for controlling rate of flow of said current when said circuit is in said open mode, sensing when said current is too low to power said light source, and boosting said circuit to a sufficient power level to power said light source when said power is too low.

Abstract
A solar-controlled light device with a circuit-control having a phototransistor, a first resistor, and a first transistor connected to a storage unit, to a solar cell, and to a current-control. The current-control has a transformer, a second resistor, and a second transistor, connected at one end of the current-control to a light and at another end connected to the circuit-control, wherein the current-control senses the amount of power and boost the power as needed to a sufficient level to power the lights.
