A housing for lighting assemblies used to enclosed a ballast. Two opposite walls include each a pair of longitudinally extending pairs of ribs that slidably receive the ends of a plate member. The walls and the plate member are made out of a heat conducting material, such as aluminum. One of the plates is mounted urging said ballast against one of the walls for coplanar abutment and maximum heat transfer from the ballast to the walls. Another plate is mounted between the ballast and one of the end walls to avoid movement of the ballast, specially during transportation. Elongated longitudinally extending heat dissipating ribs are defined in the outer surfaces of the housing walls.
