Solar energy collection system 872 preferably delivers electrical energy to energy storage device 822. However, when energy storage device 822 is fully charged, solar energy collection system 872 preferably delivers electrical energy to socket 870 where the electrical energy is preferably diverted for uses other than charging energy storage device 822. A charge controller 874 is conductively coupled to the solar cells 872 and to energy storage system 822. Charge controller 874 diverts the excess electrical energy to directly power lighting element 810 rather than lighting element 810 consuming power from energy storage device 822.
It is apparent that an assembly and method with significant advantages has been described and illustrated. The particular embodiments disclosed above are illustrative only, as the embodiments may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. Although the present embodiments are shown above, they are not limited to just these embodiments, but are amenable to various changes and modifications without departing from the spirit thereof.

## Claims

1. A retro-fit base for converting an existing alternating current lamp into a direct current lamp, the retro-fit base comprising:
a base assembly having;
a base cover having only a single hole through the base cover;
a base bottom;
a power compartment bracket;
a gasketed power compartment lid hingedly coupled to the base bottom for securing the energy storage subsystem; and
the base cover is directly secured to a lower portion of a threaded rod of the existing lamp by a nut located inside the base cover;
wherein the nut is in contact with the base cover; and
wherein removal of the nut allows the base cover to be removed from the existing lamp;

an electrical subsystem carried by the base assembly, the electrical subsystem being configured for attachment to a power cord of the existing lamp and comprising:
a plug located inside the base cover, the plug being configured to electrically couple the electrical subsystem to the power cord of the existing lamp;
an energy storage subsystem electrically coupled to the plug;
a direct current lighting element conductively coupled to the energy storage subsystem by the plug; and
a controller for controlling the operation of the direct current lighting element;

wherein the energy storage subsystem is removable from the base assembly; and
wherein the single hole through the base cover is configured for coupling the base cover to the lower portion of the threaded rod of the existing alternating current lamp.

2. The retro-fit base according to claim 1, wherein the direct current lighting element is an LED lighting element.

3. The retro-fit base according to claim 1, wherein the energy storage subsystem comprises:
a rechargeable energy storage device; and
an alternating current charging device for recharging the rechargeable energy storage device;
wherein the rechargeable energy storage device must be removed from the base assembly and electrically uncoupled from the power cord of the existing lamp in order for the alternating current device to recharge the rechargeable energy storage device.

4. The retro-fit base according to claim 3, wherein the charging device comprises:
a power transmission device; and
a power receiving device for inductively transmitting electrical power from the power transmission device to power receiving device.

5. The retro-fit base according to claim 4, wherein the electrical power is transmitted wirelessly.

6. The retro-fit base according to claim 1, wherein the controller comprises:
at least one of the following control components:
a light sensor;
a timer;
a motion sensor;
a wireless interface;
a light intensity switch;
a color switch;
a status indicator; and
an on/off switch.
