A light fixture including a turbine generator having one or more vertical-axis wind turbines (VAWTs) for generating energy and a plate located above and/or below each turbine for focusing and converging the wind inwardly. The plate is aerodynamically-designed to converge the wind onto the turbine and provide a strong wind current. The turbine generator is incorporated into a light fixture to provide self-sustaining light energy. Solar panels may be provided in conjunction with the turbine generator to provide an additional source of energy and a controller is included to manage the flow of electricity and ensure that the light fixture is powered during periods of darkness.
