To make a sustainable product and provide a temporary source of lights on during emergencies, this project aims to create a small unit that can be attached to a light bulb of any variety and connect it to a socket. Within the device is a rechargeable battery that, when the device is not connected to an 120V AC, 240V AC, or 48V DC power source, will power the light for a short period of time. The battery can be charged during the standard operation of the device and can be powered by the US and EU standard outlet voltages as well as the outlet voltage of 48 V DC from the DC House Project. This device should not impede normal operation of the light bulb and require little to no modifications of the housing unit for the light bulb. The device, under normal operations, outputs enough power to supply the 12 V DC LED light bulb for full output from the device. All the sources, 120 V AC, 240 V AC, 48 V DC, and 12 V DC allow for full functionality albeit at a low efficiency rating that could be improved. For no load scenarios, the device still dissipates a notable amount of power and is less efficient than the loaded sources but some of the issue is eased with the inclusion of batteries if no load is present. Although the device may not be the most effective or efficient, when under the right conditions, it fulfills the goals.
