6. The backup power system of claim 1 , wherein the controller is configured to receive the load current value required by the primary lighting system to sustain the load.
7. A power system, for providing power to a load, comprising:
a primary lighting system including (i) a power source having a load current value and (ii) a driver configured to match electrical characteristics of the electrical load; and
a backup power system connected to the primary lighting system, the backup power system including:
an energy source configured to supply an amount of power to the backup power system;
a charger connectable to the energy source;
a controller configured to measure the load current value of the primary lighting system and determine a backup current value corresponding to an amount of backup current that is a fractional amount of the load current value; and
a current source configured to provide the determined amount of backup current.
8. The power system of claim 7 , wherein the energy source is in electrical connection with the charger and the current source using connection wires.
9. The power system of claim 8 , wherein the connection wires are configured to connect with an external portal for programming the controller.
10. The power system of claim 7 , wherein the power source is configured to be connectable to the driver of the primary lighting system.
11. The power system of claim 10 , further comprising a switch in electrical connection with the driver and the current source, the switch allowing the backup current to flow to the load when the switch is in a closed position.
12. The backup power system of claim 7 , wherein the controller is configured to receive the load current value required by the primary lighting system to sustain the load.
13. A computer-readable storage device comprising instructions that, when executed by a processor, cause the processor to perform operations, associated with providing backup power using a backup power system to a load when a primary lighting system is disabled, comprising:
receiving input data comprising an initial current value corresponding to an amount of energy required by the primary lighting system to sustain a load at a first time;
determining a backup current value that is a fractional amount of the initial current value, the backup current value corresponding to an amount of backup current needed to sustain at least a portion of the load; and
providing, when a power source in connection with the primary system is disabled, the backup current amount to the load using a current source within the backup power system.
14. The device of claim 13 , wherein the operations further comprise measuring the initial current value using one or more sensors.
15. The device of claim 13 , wherein the operations further comprise calculating an amount of power required to sustain the load, the power calculated using the initial current value.
16. The device of claim 13 , wherein the operations further comprise:
receiving a subsequent current value corresponding to an amount of energy required by the primary lighting system to sustain the load a second time;
determining the initial current value is different than the subsequent current value; and
calculating the backup current value based on the subsequent current value rather than the initial current value.
17. The device of claim 13 , wherein the operations further comprise storing the backup current value to a non-volatile memory within the controller.
