1. An apparatus for heat dissipation for a luminaire, comprising:

  • an active heat transfer device operable to cause turbulence in an ambient fluid; and

    a thermally-conductive housing having a cavity and a first end, the cavity structured for an electronic ballast of the luminaire to be housed therein and thermally attached to an interior surface of the housing to allow the housing to absorb at least a portion of heat generated by the electronic ballast, the first end structured for the active heat transfer device to be mountable to the first end of the housing, the housing further having at least one thermally-conductive protrusion extending from an exterior surface of the housing and exposed to the turbulence in the ambient fluid to transfer at least a portion of the heat absorbed by the housing to the ambient fluid.
