A light emitting apparatus includes a light source, a unitary formed heatsink with a plurality of heat dissipating fins, and a walled enclosure that retains a light source and comprises an opening that terminates at a surface substantially perpendicular to the walled enclosure. The light source is coupled to one of the enclosure wall/s and the surface, the opposite side of the heat sink retaining the light source is a side of the apparatus that is mechanically and/or electromechanically coupled to a support structure, at least one adjacent side of the walled enclosure has a plurality of heat dissipating fins, unitarily formed with the heat sink, that extend outwardly beyond the wall's perimeter, at least one fin extends upwardly beyond the light source toward the illuminated space, and at least one through openings enable the flow of free air across at least two fins.
