Abstract: An energy-efficient lighting apparatus is disclosed. The lighting apparatus includes a ballast cover. The ballast cover includes a plurality of ballast cover holes. The lighting apparatus also includes a circuit board comprising a plurality of light-emitting diodes. The circuit board is positioned adjacent the ballast cover so that the plurality of light-emitting diodes protrude through the plurality of ballast cover holes in the ballast cover. The lighting apparatus may also include a battery for supplying power to the plurality of light-emitting diodes.
