An LED-based lighting device may comprise a substrate having a top surface with a plurality of light emitting diodes (LEDs) disposed on the top surface of the substrate. The LEDs can be arranged in a plurality of concentric rings on the substrate with each LED having a major length being oriented along the circumference of the concentric rings. An electrical driver board can be electrically connected to the plurality of LEDs. A heat sink can be thermally connected to the substrate and the plurality of LEDs. The electrical driver board can be disposed at least partially within the heat sink. A reflector assembly can be disposed on the heat sink such that the focal plane is disposed generally adjacent to the plurality of LEDs. The light assembly can generate a luminous flux greater than 650 lumens.
