invention the circuitry and light carrying tray 22 and the glass supporting extrusion members 24 it should be noted at the outset that servicing of the inventive light 10 involves the axial sliding of tray 22 relative to the longitudinal axis of the housing 12 although the extrusion members 24 are each adapted for slide fit engagement with separate ones of the side walls 16 such extrusion members 24 would not be displaced during such servicing the tray 22 has an upper surface 26 and a lower surface 28 a reflective shield 30 is carried by the upper surface 26 of the tray 22 by means of an elongated spacing member 32 it will be noted that the reflective shield 30 may include two concave portions 34 defined on opposite sides of a fold or center line 36 that extends the length of the shield 30 and is disposed substantially mid width thereof such twin reflective surfaces 34 provide reflective surfaces individual to each preferably florescent light 38 earlier reflective shields lacking twin surfaces individual to each flight result in the testing of a dark shadow not shown that substantially coincides in position with the folding line 36 of this invention elimination of the dark shadow obviously results in a more efficient lighting of the area sought to be lit the electrical circuitry generally designated 40 for the lights.
