thin lightweight material shaped to form a plurality of longitudinally extending transversely flat sections 12 with outturned oppositely disposed flanges 13 defining the longitudinal edges of the elongated support structure in the exemplary embodiment shown in fig1 flanges 13 extend upwardly a distance at least one half of the height of the curved shaped structure low transversely and longitudinally flat members 14 are attached to the outer upper surfaces of the elongated modified arcuate shaped support structures 10 to add desired rigidity thereto and to provide raceways for wires supplying current to fluorescent tubes 15 positioned in light hangers or tube holders 16 which are attached to the longitudinal members 14 the tube holders 16 register with notches 17 in the ends of the elongated modified arcuate shaped support structures 10 box like enclosures 18 are attached to the members 14 by conduits so that ballasts and the enclosures 18 can communicate with conductors in the raceways formed by the members 14 which connect with the tube hangers 16 and the fluorescent tube 15 as will be understood by those skilled in the art it will be observed that the enclosures 18 are relatively small and that they are located alongside the members 14 forming the raceways so that the uppermost surfaces of the enclosures 18 and the members 14 lie on the same horizontal plane those skilled in the art will observe that the simple compact fluorescent lighting apparatus thus disclosed can be simply and easily attached to an overhead support.
