Abstract
Aspects of the present invention further include a lighting system comprising a lighting source, a connector in electrical communication with the lighting source and an external power source, an energy storage device, an input device, and a controller. The controller may be configured to identify the presence of a load indicator signal received via the input device, determine whether the load indicator signal indicates a load-reducing state, and when the load indicator signal indicates the load-reducing state, discharge the energy storage device to maintain an intensity of the lighting source.
