A light fixture including an electronic housing and at least one optical chamber positioned on each side of the electronic housing. In some embodiments, the optical chambers are positioned a distance from the electronic housing so as to avoid creation of a thermal path between the optical chambers and the electronic housing. Each optical chamber includes a heat sink and a plurality of LEDs mounted on a PCB that is, in turn, mounted on the heat sink. A reflector is positioned over at least a portion of the PCB. In some embodiments, vents extend through the heat sink and a fin extends upwardly from the heat sink and angles at least partially over at least some of the vents. In use, air enters the optical chambers and exits the fixture through the top vents in the heat sink. The air circulates over the reflector, carrying heat from the reflectors during the process. Heat is also conducted to the air from the heat sink. The angled fins extending over the top vents provide additional surface area for contact with the air and thus facilitate additional heat transfer from the heat sink.
