Zusammenfassung:	Process and apparatus for improving LED performance are disclosed in which, in one exemplary embodiment, a lamp having one or more LEDs is powered by at least one rechargeable battery that may be recharged by solar photovoltaic panel or any number of DC or AC power sources, including a car battery or household AC outlets. The power to illuminate the LEDs from the rechargeable battery is regulated by a control circuit that enables the LEDs to illuminate for at least twice the operating time for the same LEDs and the same rechargeable battery without the control circuit.
