ABSTRACT:
A heavy-duty luminaire comprises a housing assembly of plastics having good resistance to weathering or corrosion but capable of withstanding only low structural stress. The heavy electrical components are supported with a ballast compartment on a removable ballast tray which is attached to a main bracket. The main bracket receives its support directly from metal mounting means independently of the housing. The structural load on the plastic housing is limited substantially to its own weight plus that of a lightweight reflector assembly.
