Abstract: A lighting apparatus for use in air conditioning systems for textile weaving machines utilizing supports (A) carried on the overhead ducts in longitudinal spaced relation between support columns for the ducts wherein a florescent lamp (C) is positioned within an elongated aligned housing (B) to project light evenly through a lens (D) which extends below and on one side of the duct with light being directed by a downwardly extending reflector leg (E) to distribute light in a pattern including cross-directional light evenly across the weaving machines. A cusp (F) comprising downwardly inclined converging surfaces has an apex directly over the florescent lamp (C). The method contemplates positioning a single elongated florescent lamp asymmetrically on one side of the elongated housing, and configuring the reflector asymmetrically to reflect light in a cross-directional pattern so that illumination of obstructed parts of operating machines is achieved.
