Abstract

Methods and systems described herein provide efficient lighting for use particularly in areas having unreliable and or prohibitively expensive electric grid systems. A first aspect of the invention is directed to a light assembly that includes a first input to receive input power from a first power source, a second input to receive input power from a second power source, a third input to receive input power from a third power source, a driver circuit coupled to the first input, second input and the third input, and a light source coupled to the driver circuit and configured to provide output light in response to power provided by the driver circuit. The driver circuit is configured to detect unavailability of at least one of the first power source and die second power source, and in response, operate the light source in a low power, low light intensity mode of operation using power provided at the third input. Another aspect is directed to an upgradeable modular lighting system that is adaptable for use with a variety of power systems.
