ABSTRACT:
Disclosed is a ceiling light fixture suitable for conventional fluorescent lamps. The fixture has an elongate shroud with a modified elliptical cross-section having an inverted apical crease and a downwardly facing specular reflective surface. A rigid raceway extends lengthwise within the shroud and is secured to two rigid opposing end panels which support the shroud. The raceway is substantially at the ceiling level, encloses the ballast, and provides an infrastructure for the fixture.
