Abstract: A light fixture of the present invention comprises a base, a top spaced above the base, a plurality of upright bars (channels) formed as parts separate from the top and the base and extending up from the base to the top of the light fixture for holding a series of panels of transparent sheet material, such as glass, to form an enclosure for a lamp, and fasteners for attaching upper and lower ends of each bar to the top and the base, respectively. Each of the bars is an extruded part of one-piece construction configured to have a spine, and a channel-forming structure projecting inwardly from the spine to form a pair of channels which extend lengthwise of the bar and which open laterally for receiving respective edges of two adjacent panels of said series of panels. The spine and the channel-forming structure of each bar are integrally formed as a one-piece extrusion.
