Abstract: A light assembly has a light unit mounted within a housing having a front portion with a lens for passing light from the light unit, a side portion with ventilation channels formed therein and a rear portion which completes the enclosure of the light unit. The ventilation channels in the housing side portion are formed by a plurality of fins formed by strip sections which are spaced from each and which have lips running along the inner edges thereof which extend at an obtuse angle relative thereto. The fins are joined together to form an integral unit with the channels running completely around the housing. The channels formed between the fins permit a free flow of air for ventilating the interior of the housing. The fins are angled away from the center of the housing so that along with the lips running along their inner edges such fins operate to minimize the passage of light through the housing side portion.
