Abstract

A light fixture has an outer housing having a top outer wall with first and second outer edges. First and second outer side walls extend substantially perpendicularly from the first and second outer edges. An inner housing is disposed substantially within the outer housing and has a top inner wall that has first and second inner edges. First and second inner side walls extend substantially perpendicularly from the first and second inner edges. A lamp receiving socket is attached to the inner housing. An opening in the outer housing is adapted to connect to a ventilation system. A first channel is defined between the top outer wall, the first outer side wall and the first inner side wall to receive air from the ventilation system through the opening. A second channel is defined between the top outer wall, the second outer side wall and the second inner side wall to receive air from the ventilation system through the opening. The first and second channels have a combined width that is approximately ⅓ the distance between the first and second outer side walls.
